VN - Ren'Py - Oppai Odyssey [v0.4.4B] [Cryoxxx]

Oppai Odyssey is an ambitious space adventure that never forgets it's also a porn game. Weaving an engaging story, characters with their own personalities and goals while also being generous with sex scenes is a difficult task. But again and again Oppai Odyssey proves it is up to the challenge.

The writing is engaging and while some might complain it's verbose - especially when it's describing sexual encounters - if you're fond of writing that attempts to pull you in rather than a little side-dish for the visuals then you're gonna enjoy it.

Character dynamics is alive and present within the game and as the story progresses it becomes more nuanced. You can choose to take on a more dominant or submissive role with the girls, and for the most part this is done well. A problem with almost all the games that attempts D/s dynamics they all go from 0-100% at the blink of an eye and almost always overshoots. That is not the case with Oppai Oddyssey where it's fluid and plausible. My personal gripe with it was that sometimes these Dominant and submissive moods mesh without you having any input in it and the result is awkward and artificial.

The art is amazing and the animations fluid, not much to add to that except well done! And look - the game isn't named Oppai for nothing.

There's a free roam aspect to the game and it's difficult to say whether that's the brunt of the game or not. Personally I found the first time you get into sandbox mode to be clunky and the game lost a lot of its steam, but that's me nitpicking.

All in all - a game that's well deserving of a 5 star.

Oppai Odyssey [v.0.3.8]: 4 stars. Oppai Odyssey is a project of love, and by far the most interesting and well-made game in the space harem genre, insofar there exists one. The story is relatively simple, the main character is commissioned on a ship. Alongside his childhood friend Lym, and the doctor-examiner, Dr. Clermont, the protagonist joins the ship’s engineer, Noel, to go on space missions in search for distant planets and wayward ships. Here, flag officers Mars (and Toyotomi) issue directives and steer the general course of the journey. Nyx, a wizard alien, joins the fleet, and side characters from other ships chime in occasionally, Sybil and Yoo-ri, as well as Alex, a male crewmate. Most of the time is spent with the three main girls. As the title affirms, the women are all busty and well-endowed, gifted with huge, massive tits, toned abs and shapely thighs and asses. Since the art is stylized, the character designs aren’t too distracting. Perhaps an acquired taste, the designs fill the gap of unrealistic body frames which manage to look attractive. For the main character, he’s a typical harem protagonist. He exhibits a lack of experience with his job, and his nice, innocent personality is a nice foil to his coarse, primitive sexual urges.

Life in space is slow. The opening sequence reflects this, as the prologue takes some time to get used to. Events are repeatable, and menial trivialities, eating, training, sleeping, etc. are the bread and butter of unlocking scenes. Though this grind relaxes as Oppai Odyssey opens up, with the overhead map, the actual gameplay part is a hindrance. Sandbox games are inherently boring because of the lack of structure disguised as structure. Thus, grinding is part of the game's DNA, and meaningful progression will take a while. Going to bed is a chore. Another persistent annoyance is how the menu defaults to the captain’s log and not the save option. Presently, there is an attempt to add some dynamism and color to the static navigation through the use of minigames, specialized paths, and stats. For example, there’s an affection and lust meter with the girls. But in the end, the form dictates the pacing, and there’s more clicking than should be required of an otherwise straightforward game.

It’d be a shame to be otiose and complain about Oppai Odyssey’s gameplay however; it’s only a part of the overall experience. Celebrations are in order. The game is a faithful collection of sexual fetishes and kinks which the author finds gratifying. As a result, the selections of fetishes feel inspired, crackling and bursting with a joyful, youthful energy. From the get-go, unconventional fetishes are introduced: female domination, urination, use of drugs/aphrodisiacs, tentacles and non-consensual sex. There’s a sort of Sadean excessiveness to it all, owing to the unreconstructed anime tropes the writing inherits. Each of the women are broad sci-fi archetypes, Noel, the drunk mechanic, and being the tanned muscle girl, Dr. Clermont, an intelligent, secret, submissive pervert, and Nyx, a sadistic type. There’s Amazonian alien women. Recognizable, not at all recherché, and the style sets it apart, especially with the commitment and all-in attitude on behalf of the author. The mood is infectious; we get swept up by it. The animations are beautifully made, looped, and thought-out, a favorite. One wishes these scenes would go on longer. Likewise, the quality of renders are great in story events, the lighting is subtle, the depth of field is tastefully used, and the general look of the game is appealing, and easy on the eyes.

Science fiction tales tend to suffer the pitfalls of genre storytelling: the overemphasis on the setting, world-building and lore, and favoring plot over characterization. Thankfully, the writing here does not veer off in this direction, instead, opts to ignore story altogether. The story is the setting, not the other way around. The plot is largely set dressing, a self-parody, and a harmless one at that. No stargazing, no philosophizing. If anything about Oppai Odyssey feels ordinary, what sets it apart are its strengths. Look to the originality of the sex scenes, the imaginative use of fetishes and Illusion assets, the cinematic, manicured feel of the animations, and the obsessions of a singular vision put to work. Oppai Odyssey feels so malleable and fresh; every update brings forth a slew of new content, and improves upon old renders, remaking or extending events. With a bit of polishing, restructuring, and tightening up the story and characters, the game can go in any direction it wants to.

Version: 0.3.8 Public

This is a decent game.

The story isn't that great. I can summarize it in about two or three sentences, but I won't.

The game is really just clicking on new events and see what each character is up to, with some occasional really good sex.

At least this game didn't make it a grind. Pass time, click lit up thing, repeat. But all of them were new so it didn't get too repetitive, just... also not substantial.

Sex: 5/5
Model art: 5/5
Frequency of sex: 4/5
Choices: 4/5 (I like that I didn't have to go along with things sometimes)
Story: 3/5 (Plot is an afterthought for most of the game)
Characters: 4.5/5 (Missing a range of personalities but they felt like people.)
Enjoyment: 4/5 (Hot scenes. Too much downtime of nothing going on or pointless talk.)

Fetishes: The one unexpected tentacle part was hot, imo. The pregnancy tag... eh. Barely even relevant. Disappointingly so.

Worth playing?
Eh.
It's not bad but not great either.
Try it if you have time. You might love it.

Review of v0.3.8

A game I really wanted to like, but as the updates keep coming out, it gets harder to defend against some of the flaws.

Graphics: Best thing about this game. Graphics are well done.

Plot/Writing: Terrible. This is supposed to be a military vessel, but it feels more like a pleasure cruise filled with horny high-schoolers. There is no discipline on this vessel, which a military expedition should not be like. I will touch on character's writing later.

Sounds: Good

Sex: Starts off vanilla and stays that way for a long time, but quickly, without warning, gets into really hardcore content (rape, tentacles). Urination also gets added, not extreme, but no buildup to it.

Characters (biggest issues):

Some of the characters are great. Lym and Noel are fantastic characters.

However, they are overshadowed by the terrible characters.

The doctor: she drugs the whole ship so that they get horny. This should not happen under any circumstance, and the MC should have ditched her since this is not the mission and goes against basic ethics.

Nyx: She starts off bad, which is fine since that is her character, but just as she is getting more likable, she rapes a LI. Yes, the scene is technically avoidable, but it is so out of place and ruins anything since she becomes a potential rapist for the rest of the game.

Sybil: Almost likable, but she just becomes a sex toy for the MC to use.

MC: I can typically overlook a stupid, submissive MC, but this MC is just too hard to defend. He is suppose to be on top of his class for the academy, but he cannot lead a crew, resist his urges to have sex (gives up valuable military information so that he can finish cumming), cannot withstand basic torture, lets his crew do whatever they want, gets captured easily, allows someone on his ship to rape another (not an exaggeration), allows his crewmembers to be drugged, etc. The list goes on, and he should have been a janitor at a movie theater with how well he does here.

It is possible to fix most of these issues (and I hope they do get fixed), but it would probably be too much work.

in my honest opinion, i would recommend this game.

Game UI 3/5 - looks appropriate. needs some tweaks / improvements too to make the game a bit compact because i find some delay when tapping the minimap

Storyline & Amount of Content 3/5 - not sure how the storyline gonna unfolds, the contents is vary, too. i think the dev team needs focusing on the storyline and the characters that involves around it.

Writing 3/5 - the writing is good, but sometimes there's typo on few sections. acceptable though.

Character 4/5 - some character designs and map design may needs some improving. overall, looks nice.

Animation & Rendering 5/5 - just great.

Sound & Music 3/5 - its nice, gave me some relaxing vibes when playing the game. maybe some original tune for the game would be great addition

This is one of those games that just doesn't have too much substance. First off, you are told that the MC is the top of his class so here I was expecting some exceptional individual. But in most situations, he doesn't know what he's doing and gets pushed around by everyone.

The models look somewhat nice but they are a bit choppy. For the most part, the other characters' personalities are fairly bland and are just there to be all over the submissive MC. The story itself has some promise but it really doesn't deliver and ends up being very boring. The sandbox element is overall frustrating as I just wanted to advance the plot but there seems to be no way to do so other than spam clicking the women over and over again in hopes that the story progresses.

In my honest opinion, this is one the best games I have played on this site and 100% recommend to all those who haven't tried it to give it a try.

In terms of content:
H-scenes: 5/5
Story Line/Plot: 5/5
Character 5/5

What more can I say except this game is great and has so much potential and expansion when looking at the possible paths the story has.

[v0.3.7R Public]
I'll be quick and clear with this review.
The game is amazing, if you like harem and sci-fi this is perfect for you. I loved the story, music, animations, renders, hot scenes, characters personality, beautiful girls, dialogues, environment, sexy aliens, Spike's humor, it's just awesome.

I really like the direction that the dirty talk has gone on this game recently. and as far as HS2 goes, this is some of the best out there right now. I hope this trend continues!

Sibyl is probably my favorite, I hope we get to go on a date with her like with Lym.

~ Art? 4/5

The ship and planets look pretty good. Nothing groundbreaking, but solid.

~ Character Models? 3/5

This one was a little tougher, the models look good, really good even, but the characters are just so generic in body shape that I couldn't feel all that excited for it; just the usual hourglass figures and comically large breasts.

Also, in some of the shots, the characters look a little blurry? I guess would that would be a good way to put it. Not massively, but sort of like the edges of their body are fuzzy. It's weird.

~ Characters themselves? 3/5

The main character is typical trash you see in these games.

He's supposed to be the top graduate from his school- so talented that he's made a Captain of a ship right of the gate, yet in every critical moment, he gets pushed around and made a fool by everyone.

Even in critical situations where his friend's lives are potentially on the line he can't grow a pair and do something.

Lym is the one character I don't really have many complaints about, other than the fact she's a bit of a bitch sometimes for seemingly no reason at all - especially after Nyx enters the crew - which throws me off a little. But she's fine other than that.

Dr. Clermont suffers from the overused 'comically huge breasts syndrome' that are so unrealistically big that they're more of a turn-off than anything else. As for her personality? Eh. The author tries really hard to give her this like kind motherly vibe, but she's such a slut that it just doesn't really work and makes her character weird.

Noel is pretty good too, she's the most 'normal' character other than Lym. Other than the fact she wears a loose tanktop esq shirt and no bra that leaves her breasts on full display 24/7 which is honestly kind of creepy and takes away from her allure, she's not bad.

A quick note on that since most authors don't seem to get this. Woman. Do. Not. Need. To. Dress. Like. Sluts. To. Be. Appealing. Did you get that? Part of the allure of beautiful women is wondering what they look like under their clothes. When everything is on display from the start it's kinda boring.

Anyways, continuing...

Nyx as a character isn't that bad, it's just the circumstances around how she comes to be a part of the crew - and this also stems from the MC being trash - that make me dislike her. I'll touch on that later though.

I don't know enough about Sybil, Yoo-Ri or Momiji to comment on them. And Kali is just your typical boring 'bitch for no reason' character.

~ Sound? 3/5

There is music which is a plus, but I feel like most times it doesn't really fit the theme of the game so it's meh. Good that it's there but could be better. I'm drawing a blank and can't remember if there are other sound effects, I think there were a few, but nothing extensive.

~ Animations? 4/5

This is the one place where the game actually shines. The animations are great, if not a little repetitive. Some more variations would be nice, but the ones that are in are great to watch.

~ Dialogue? 2/5

The little dialogue there is, is fairly well written, but the first part of this sentence in the problem. There is next to no unique dialogue between the characters, just the same repeatable scenes at different times of the day leaving the characters themselves and their interactions with each other feeling incredibly shallow and uninteresting.

~ Story and Worldbuilding? 2/5

The only reason this category gets a two is because of the space exploration part of the story. As a lover of Mass Effect, these games hold a soft spot for me. Unfortunately, that's where the positives end.

You start the story in some sort of post-graduation meeting with your teacher that leads to sex with her afterwards, however, with zero insight into their relationship or development other than a couple of background lines the scene feels very unnatural and forced. Sort of like the MC found a prostitute for some last-minute fun before departing earth.

After that, you have some cringe-worthy interaction with Alex (who I didn't mention earlier because they're such an out-of-place and poorly-written anti-protagonist character) who will be part of your crew but shows you no respect.

He also tried to flirt with and get with every female in your crew as the story goes on which I don't know if it's supposed to be funny that he gets rejected by everyone or we're supposed to hate him more because he's going after 'our' girls, but again, it just falls really flat.

Following that, you meet with the Docter who messed with your implant without telling you anything beforehand, and even if she did it for a good reason, we don't know that at the time, and so the fact that she does that and the MC is nonchalantly like yeah, okay, you have huge tits, do whatever you want, it's kind of off-putting in its unrealism.

She also gives you some self-created formula that is supposed to help with acclimating to space - great - only it has a side effect that is- you guessed it! An aphrodisiac. So original.

Anyways, after this, you finally get on this ship which is just a point and click sandbox where - as I eluded to earlier - is basically just story event after story event with each character with next to no development or dialogue inbetween which leaves everything feeling incredibly rushed.

I mean, your basically fucking- or at the very least doing foreplay with every girl after only a couple of events with them. It's seriously unsatisfying.

As for the missions themselves, I won't spoil too much, but I'll tell you my issue with them.

As for the first planet where you meet Nyx, she is what I have an issue with. As a character, she is totally useless and instead gets in the way of the MC. I mean, in their first meeting she uses her powers to knock him out, and when he wakes up he's tied to a char and - of course - naked. She uses her powers to summon a ghost hand that jacks you off and also uses a spell that makes it so you can't come until you tell her what she wants to know.

Now, if you thought our 'impressive' MC who was so amazing that he became a Captain right out of school would put up a fight, you'd be disappointed. You are left with no choice other than to sing like a canary to her telling her anything she wants to know and begging her to let you cum. So impressive of the MC, eh? Really seems like captain material.

Her only 'contribution' to the group was getting blood samples from the sick people in the village, something the MC and Lym could have easily done without her.

And to make things even funnier, when you come back with the cure for the people, you find that they were all captured by what I'm assuming are orcs/goblins- yes, Nyx too, who is supposed to be so powerful! Utterly useless more like it.

But of course, the MC and Lym save them all and then with - once again - no say in the matter, the MC invites Nyx with them on the ship. Man, what a useful companion. She did so much to prove her usefulness in their short time knowing each other.

Anyways. Onto the second mission that I couldn't finish because it was just so awful.

So, to start off, you go down onto another planet to check things out, scan plant life and animals, see if it's a habitable place, the usual. Where things go bad is at night. Your group is attacked by the locals who want to know who you are - fair enough - so you are put into a cage and hauled to their camp where you are supposed to meet with their Queen and try and earn her trust so you can not only be free again but hopefully get some allies in the process.

Seems reasonable. Until it isn't.

The head of the scouting party that captured you sends you off with two other girls who are to find you suitable clothing and some food before you meet with the Queen. While in their house, one of the girls leaves to go get on food, while the other gets you some clothes. Well, she gets you some clothes, puts them on the table beside you, but before you can put them off she rips your underwear off and quite literally rapes you.

You are unable to fight back due to the whole being a prisoner thing for one, and two, without your consent she lathers your dick with an aphrodisiac so even if you wanted to say no, you cannot as you're driven by lust. Man, such compelling storytelling.

So anyway, in the middle of getting raped by girl number one, the other one catches wind of what you're doing and decides to join in too! And, due to a mix of the aphrodisiac and the MC being a spineless cockroach it ends in you fucking both of the girls in what I assume was supposed to be a 'sexy' scene, but really, it's just kinda fucking gross.

So, after getting raped by those two girls, you're finally off to meet the Queen, maybe things will get better from here? Yeah. Fucking. Right. Because guess what! She rapes you next! And you have zero fucking control over any of it.

At this point, I was pretty much done. I threw on an auto-clicker to see what was a little further ahead in the game; see if there was any saving grace, but almost immediately after getting raped twice, the MC then willingly has sex with the woman who captured him in the first place, and that was the last straw for me lmao.

Anyways. To wrap things up. This game does some things well, but the writing is so beyond trash that I'm honestly shocked it has as high of a rating as it does. It is seriously undeserving of it.

was working on a bigger review of this game. but it became too complex and with 60 other reviews on the game, i am guessing not many of you are going read it all anyway.

so the Short version:
if you look at all the other reviews of the game they are nearly all 5 stares. there is a reason for that. you just have to hold out past your first mission and i am sure you will start to see it too.

the only word of warning i am going to give you is play this when you have time to lose, and not like me that missed a day at work sins i was up all night reading this ting.

Updated review for V0.4.1a

Update -Moved down a star. The more recent updates have left me... concerned about a few things. I plan to rewrite the review at some point, but I want to let a few more updates drop to see where things shake out (plot took a very sudden turn, gotta see what happens after this cliff hanger). Going to leave most of the review as it originally was for now, but see where I start critiquing it for a few new thoughts.

I feel like there are relatively few sci-fi visual novels on this site, and even less of them that I'd actually call good. However, I say with confidence that this has become one of my favorite games on the site.

Sci-fi is one of my favorite genres in general. This has many things I'd want out of a good AVN set in that genre. Exploring the stars with your lovable crew and meeting hot aliens (and recruiting some of them) along the way. Of course that's a bit oversimplified, but gives you a general idea of what's in store.

Let's talk sandbox mechanics. This game does sandbox great imo, and I wish more games would follow this formula. You have your ship which essentially acts as your hub for you and your crew. Different events pop up for all the girls throughout the days until you eventually get to a plot progression point. Then you typically go out on a long mission that plays out more like a regular linear VN, which progresses the main story. Once the mission is over, it's back to your sandbox ship filled with new events and usually a new crew member on top of it among other things. I love this. It's very comparable to something like Mass Effect (which I just realized upon writing this review). Your ship and crew feel like they are steadily evolving and reacting to the story along with you, and aren't a bunch of bubble waifus that don't interact with each other.

The events themselves are also really great. Both the lewd ones and the more normal ones. I think one of the best compliments I can give this game is that out of the literal 100+ games I've played on this site, it has some of my favorite lewd scenes of any game I've played. They are just really well put together (the scenes with our lizard wife just hit different man). What I also really appreciate are the small scenes thrown into the mix. Eat food with crew members, playing video games with a space elf, helping the engineer around the ship, etc. It just adds a lot of life to the characters and feels nice to see.

All of the love interests so far are exactly that: lovable. They have personality, good dialogue, and are actually developing characters. A little quick on getting cozy with the MC, but not so much that it feels nonsensical to me. Plus it's a lewd game after all. On top of that the designs are great as well imo. Something I also really like is that we have actual sexable aliens that look alien. It always irks me when every alien race in a sci-fi space game look like slightly altered humans. Yes there are space elves and space cat girls in this, but also some more alien looking ones as well (hopefully we get some more on the crew at some point.)

Critiques: I had mentioned in my original review that sometimes it was a bit hard to connect with the MC. His dialogue lines didn't always hit me right I suppose. This problem has now gotten worse in the last few updates for me. The MC is approaching unlikable territory in a few regards. He's flawed, and I get that, but I'm not feeling the way the flaws are being handled. I'm still giving it time as there was recently a rather drastic turning point in the plot, so I'm going to wait and see how that shakes out to really judge it.

I'd still also like to see more multi-crew events. I think it would be nice to have things like a movie night with the whole crew, or maybe eating dinner with everyone as an example.

TLDR - This still is one of the best sci-fi AVNs I've played, and still a favorite of mine. There's a lot to like about this game. Here's hoping the next few updates clear away my concerns.

TL;DR
Download the game, if nothing else for the marvellous animations!

This could quite possibly be one of the best porn games I've ever played!
And I've played quite many over the years.

The story is compelling, the scene compositions are excellent the animations are incredible!
Those put all other animations I've seen in other games to shame, if none of the tags draw your attention, just play up on to the first sex scene and you know what I mean and there are a lot of them as well!
Everything is animated, I won't spoil this but you will be amazed!

I started to play this game this weekend and played it until the end.
The pacing is good too, even though the story want to move you further you can do all the interactions of the women at your own pace.
Do watch out for the hidden items that unlock the gallery. I still miss a few and I have no idea where they might be.
Part from that there's no grind, even though the women have affection and lust ratings those doesn't seem to come into affect, or at least what I know.

[edit]
It has visible pregnancy and one preggo sex scene!

@Cryoxxx You got yourself a new Patreon!

Rated: 5/5
Based on v.0.3.7R Public.

Haha, oh my god. Somehow this was just the exact right amount of ridiculous versus deep space story and nice conversations. Made me feel really good throughout, very immersive.

Girls were great, believable personalities and unexpected lines. Great clothing choices. Very funny.

Great sex scenes, nice looking poses and sweat ;-)

Immersive and weird stories until now, was really impressed by the creativeness. Also the occasional sprinkle of darkness and seriousness did add a good amount of flavor to this one. Using the pain and almost death from the "lust potion" early in the game to show that you're capable of that flavor was a great idea.

Keep it up! Looking forward to the next update.

Also, this is one of the few games in which I find the sandbox approach not annoying and even enjoyable.

Game is great and i mean it! The story is getting more and more interesting in the later stages and the dev is even reworking the prolouge now. The characters are uniqe and i really like the writing.

Can not wait for more updates!

Version: 0.3.6 Public

Very fun little game! The scope is kept in focus and the events that the MC gets into serves the plot so far. Dialogue is good and the renders and animations are very high quality.

A little on a the short side when it comes to actual content, but I like what is here so far. Probably took me about 4-5 hours maybe to finish what is here. However, Cryoxxx has done a really good job setting up the tone and pacing of this V/N.

The only issue I have is that some of the dialogue with the MC are a bit all over the place. How he acts with each of the different LIs makes him feel like a different person to each of them. This might be a personal preference thing though, as I enjoy MCs that maintain a personality rather than be a stand-in for the player.

Another thing to note for people who are into this: so far, the LIs don't interact with each other in any sexual way, so, if you are into group stuff, you might be let down. That's not to say there won't be, but, only one three-some happens in the game and it's with minor characters.

Since this is still pretty earlier, I will be waiting to see what is next. Recommend trying this out if you like Sci-fi themes and harem games.

I'll give you all the TL;DR at the start, like it's supposed to be: Original Star Trek, but where you get to actually see Kirk bang all the hot alien chicks in probably the best animation I've ever seen in an AVN.

Now, on to my long winded review:
Contrary to a lot of reviewers, I don't find sandboxes particularly annoying, but Cryoxx's take on it should appeal to even the most diehard KN fan. There is no grinding for any sort of currency or anything like it. Instead it's a way to let the player pace the vignettes in a way that caters to their preference. This is really where the Star Trek vibes shine through, as most if the events stand by themselves, some create mini arcs, but they all tie together to move the characters forward as they travel to their objectives.

Speaking of characters, of course all the women are beautiful, but Cryoxx has managed to give each one a unique personality that each really adds something to the crew. And as the game updates, I find even the characters I didn't like have grown on me, with some managing to go from pretty much last place to top three with this last update.

I am sure others have better covered what the fetishes are in the game, but I do want to comment on the fact that Cryoxx has managed to not only write femdom content I find hot, he's managed to write femdom content I preferred over the well written maledom path he wrote.

In closing I want to talk about Cryoxx himself, as I think the developer is often overlooked, especially in indie games like these. It's clear that he not only cares about his game and characters, but he also cares about his fans. He listens to them and tries to incorporate their suggestions, as long as they don't interfere with his vision for the game. He is also one of the most down to earth and approachable devs I have encountered. He's often hanging around in his discord server (and many of his fellow devs'), where he's actively talking and memeing with everyone else.

excellent game. a lot of earlier reviews critique the game for being heavy on fdom and a bad sandbox, but later versions changed that a lot: fdom seems minimized in later sections of the game, unless the player decides to choose submissive options that are clearly indicated. the sandbox is basically non-existent, the player just clicks on events in the order the player wants to view them in. and the game has superb animations as well. easy 5 stars, an underrated gem for sure.

After my first playthrough of Oppai Odyssey, I can honestly say I didn't think I'd ever be reviewing this game. That's because the playthrough was about 15 minutes long, and covered 3/4 of the prologue. At that point I'd decided I didn't like the MC, the renders were OK, and the setting was pulling me out of the story. So I quit and uninstalled.

Happily for me, a month or so down the road, another VN player who had given me some good recommendations before suggested this game. I told him about my first experience...and all he said was; 'Keep playing'

Boy am I glad I did. After some tentative steps out of the gate, Oppai Odyssey improves in leaps and bounds, to it's current state where it's one of my favorite visual novels.

So, will you like it?

Pros:
The Renders - Oppai Odyssey is a great looking game. After a bit of a shaky prologue, the visuals get better, and then continue improving the longer you play.

The Characters - I don't want to spoil anything, but while you may find a few tropes explored among the crew, there is also a lot of originality and deep character building going on.

The UI - Generally I hate sandbox games, but this game does a nice job of straddling the line between Sandbox and Kinetic Novel. The story is linear in progression, but allows you to make choices within it, including when to visit the various ladies. There is no time gated content, no annoying grind, and no immersion breaking repetition. If you have to have sandbox elements, do them this way please.

The Kinks - I normally can't stand fdom in games, and there are certainly some overtones of it in this one, but it is generally up to the player to engage in it or not. If it's your cup of tea, I hear that path is highly enjoyable...if you're not into it, there are plenty of other interesting routes to travel, and much as the renders have improved, the game is getting bolder and more interesting in the kinks you can enjoy.


Cons:

Audio - It doesn't detract from the experience, but as of the current build it's not adding much either.

Main Character - He's serviceable as a stand in for the player, as a believable starship Captain he still has a good ways to go.

Slow Start - Around the time you get to your first planet and pick up Nyx the game really starts to take off. Previous to that there are good scenes sprinkled in with others that are less good.


Final Verdict:
Oppai Odyssey in it's current version 0.3.6 is a great looking game with a deepening story, a roster of beautiful and interesting women, and a developer who is clearly committed to releasing updates on time, and not just continuing to put out work, but continuing to improve it.

Edited to Add:
As of the 0.3.7R rework of the prologue and many areas of the story, this game has become simply one of the best AVN that you are going to find out there. I can't give it more than 5 stars, but I would if I could. Stop reading these reviews and go play it.

Review of Oppai Odyssey [v0.3.6]

Well then, hello there dear traveler! Let's see what can be said about this game and if it actually is for you.

STORY 3.75/5:
Story wise, the game has somewhat of a clumsy start and would recommand to revisit the first half of the game and adjust it. What I mean is that the first half feel (at least in the case of MC) like the game's trying to mend together two absolutly opposite personalities and it really doesn't work that well for the game.
Now that those thorns are out of the way, lets talk about the story and characters in it. There is fairly large variety of girls you can (and must) ship your MC with in the progression of the story. There are cute girls, shy girls, annoying girls and other variants that give the story some nice flavour, ALTHOUGH I can see, why one of the characters might scare some ppl off... I was nearly one of them, but my mood sky-rocketed through the roof, when I actually got to the part where you start to get your deserved revange.
Overall rating of the story is 3.75/5, thanks to the a bit hectic start, but this rating is probably going to change as Mr. Dev is planning on revisiting the prologue, which, if done correctly and no doubt it will be done correctly, will change my rating which I expect to go up to 4.5/5.

CHARACTERS 5/5:
Characters in this game are just... amazing. Every girl has her own personality and day to day life issues that she is dealing with. Earlier I would fuss over one character, that kept on pis**ng me off, BUT my opinion was changed after I got to the later part of the game where you actually get to walk all over her instead. Well back to the characters, as I wrote earlier, there is incredible variety of personalities from a tender and shy girl that is your BF through one that hides her insecurities behind funny mask (also there is alcoholism involved) to a girl that is bossy (two possible ways, either you are sub or dom, only sad part is there is actually no way to romance her on equal standing, but oh well, we can't get everything we want)

GRAPHICS 4/5:
The game shines on it's animations and I would say it's one of its selling points. They are beautiful, what else could I say and althought there are sometimes some dislocated joints it is all good and forgotten in the end.
The main downside of this, is that it seems that there was not much of the budget left for backgrounds, where really only background worth mentioning is on your spaceship.
Overall I would rate graphics of this game as a solid 4/5.

Final rating:
This game deserves solid 4/5 maybe even 4.25/5. I would strongly advise devs to revisit the actual start of the game and redesign it a bit, but as for cosmetics, those could be done... well, before the final launch. As always take my reviews with grain of salt as it is just my opinion and everyone should make their own opinion of the game, because I'm just a scrub lord of a reviewer.
Would I recommand you play this game, dear reader? Yes... definitly big, fat YES.
