Thanks! Since frojack and you have played most of the ones I mentioned, I'll list some more of my favorites. Some of these are not quite as romance centered as the first list so I didn't include them initially, but obviously romance is a part of it. A few tend to be more story focused, with romance as a major bonus (Depraved Awakenings, Deluca Family).
- City of Broken Dreamers - Looks like AAA game to me. The animation is first the best I have ever seen from a RenPy game, the story is very strong where the MC is hired to kill a genetic mutant with unusual powers, and ends up trying to save her. The characters are pretty interesting. Not super-deep like some of the others, but get carried along with the story, and the sexy scenes are a major bonus.
- Depraved Awakenings - Same developer as City of Broken Dreamers, great story, romance is a little stronger, very hot scenes, and some of the characters have good depth. You owe it to yourself to play this and CoBD if you haven't already.
- Estate Dominate - I am usually not at all into female domination games, but the way it is done here, with the MC basically imprisoned by a cast of women in their mansion, waiting for his chance for revenge, is really great. For me, the scenes with drawn out teasing, and the mystery of what is really going on is top notch. You don't know who to trust, if anyone, and what is going to happen next. Really keeps you you your toes. Not really any romance at all, but a good game. Try if for 15 minutes to see if it is your cup of tea. I really like it. If you have to have a game where the MC is in total control at all times, you won't like it. Otherwise, it is really fun and exciting.
- Summer's Gone - Amazing game so far, where you are a witness to a car accident and the victim is in a wheelchair and falls in love with you. Many other hot characters. Would be much higher on the list if the development were not so sloooooowww. The last update was 1 year ago. The dev says that future update will be a lot faster. It is worth giving it a chance. If the dev can put out updates a little faster, it will be one of the top games here.
- A Mother's Love - Really great. You slowly build up a relationship with your girlfriend's mother, who is hesitantly and then more and more enthusiastically into it. The characters are great, and the scenes are hot. The story is good too. There is some mystery as to what exactly the girlfriend's father is up to with his business and personal life, that keeps the story fresh. The girlfriend is a little boring, but probably that is intentional to make the mother more appealing. The sneaking around with the mother really adds to the excitement of the story, I think.
- Avalon - Pretty fun. Not the deepest story or most in depth characters, but the relationship with the MC and his niece is warm and sweet, and there are a few other characters that add fun to the story.
- Being a DIK - Same developer as the amazing Acting Lessons. You are a new student in a university pledging a fraternity. For me it has something missing, regarding how close you can get to the characters, but it is still in heavy development so we will see. Still, by any objective measure, the animation and renders are top notch. One small step behind City of Broken Dreamers, but still amazing. Try it, a lot of people really love it, and I do enjoy it. There is a lot of humor some, better than others.
- Dating my Daughter - So famous, I probably don't even have to mention it. One of the earlier big games here, but undeniably fun to play. The daughter is a little too devoid of personality, especially after the first 3rd of the game, and it gets a little repetitive, but I always enjoy each update anyway.
- Unleashed - Unleashed is great fun, and really funny at times as well. It is where my avatar is from
. It seems like a pretty stereotypical story of a young man (the MC) living in a home with an oversexed single woman and her hot daughters. It doesn't really have a huge amount of romance, which is why I didn't put it on the first list, but it is really enjoyable to play. I said it already, but the humor is really nice to see. Most games don't have much, or the humor is bad. I don't quite know where the story is going, because the dev hints that there is a whole separate layer on top of what we see, some sort of mystery that has not really been revealed, except in slight clues. Development is not very fast, unfortunately, and it looks like there is a long way to go, but if you are patient, really a fun game. I love it.
- Dr. Amana, Sexual Therapist - Wow. Would be one of the top games here in my opinion if the updates were not so slow and short. I love all the characters, who each have a unique personality, and the story is actually quite good, which is rare in VNs here. You are recounting your life and your mistakes with a therapist, and your choices actually have a major impact on your relationship with each character, which is nice to see. You really have to play the game at least twice to get all the content. I would say it is only about 15% completed, but there is still a decent amount of content so far. There is a lot of humor as well, which is appreciated. The dev is a great guy, who is very active here and takes a strong role in teaching others rendering, and even holds frequent live streams of his work. I think he is doing an amazing job, but he has a real 9-5 job, so his time is limited. If I could speed up time about 2 or 3 years, this game could be one of the top here. If you have a lot of patience, it is a great game to try.
- Fetish Locator - Totally unique. I love it. You are a student that is semi-forced into using an app to get points by secretly doing lewd activities with other students with the same app. The concept really works. The game has some unusual (to me) fetishes that normally I don't like, but are fun here. All skippable, if you aren't into it. Plenty of vanilla content too, so don't be put off by that. The characters aren't super deep, but it is a lot of fun, and I really enjoy each update.
- Haley's Story - This is an odd pick. If you have played it you know what I mean. Started out great, probably one of my favorites, but some choices in the story have steadily moved it down in my rankings. You live with your "childhood friend" who is in love with you, and has a bit of a dark past. There are also a few other characters, but the story really centers on Haley, hence the name of the VN. Haley as a character is really appealing, and probably one of the most realistic portrayals I've seen here. Ultimately, I really like it, but the later updates are not quite as good as the earlier updates. I think this suffers from the same problems most VNs have where the Dev doesn't know what to do with the story once you get the girl, so it is a bit repetitive. I personally would have taken a lot longer for their relationship to develop, but that is just my preference. It sounds like I am not recommending it, but really it is a very good story, just be prepared to get a little underwhelmed by later updates, but I have to recommend it because I loved playing it for a long, long, time, and even now the updates are still enjoyable.
- WVM - You have probably already played it. It is one of the most popular games here. You are a top basketball talent at a lower tier school, so everyone loves you. A huge cast of characters, all the women are romanceable except for 3. There are 51 at my last count. Whew. It is really hard to keep track of them all. Lots of hot scenes. Not the deepest story. With so many characters, you really don't get to focus on romancing one or a handful, but give it time. The MC is perhaps too popular with women to be even slightly believable, all women he encounters pretty much stop everything to be with him despite him already having a crowd of women with him already, but if you can suspend your disbelief, it is quite fun to play.
- Alexandria - A previously violent MC, meets the daughters of a gangster and slowly becomes more and more part of their lives. Despite the subject matter, a surprisingly sweet story. I like it a lot. The characters aren't extremely deep, but the romance is good. The MC is a little passive when it comes to women, but if you don't mind that, you will enjoy it.
- Become a Rock Star - Interesting story, several really good characters. It isn't my top-top favorite, for some reason, but it is undeniably good. The characters aren't the deepest, and don't have a very complex personality, but it has a lot of hot scenes, and I look forward to each update.
- Element-174 - This one is very underrated in my opinion. I don't want to give away the story, but it starts of as a stereotypical guy (the MC) going to college and meeting a cast of hot women. Things eventually aren't quite what they seem. I really like it a lot. Good writing, interesting story, a bit farfetched, but easy to look past the realism of it. Renders aren't as polished as some of the others, but there are several characters with some depth, and I really want to see what happens next.
- Heavy Five - Great science fiction setting. Had a huge development hiatus (a year or more? I can't quite remember) where the dev redid all the renders and updated the story. It is a lot of fun to play. The large cast of characters means that you can't really get to know any that well, and it is more story focused-than romance focused. But give it a chance, it has a lot of funny parts in it as well. It has a long way to go, and could be one of the best here eventually.
- Harem Hotel - I didn't really like this very much at first because of the sand-box nature, though it is very forgiving and not hard to know what to do. But it was so well recommended by its fans, that I stuck with it. It has zero grinding, so it is one of the few sand-box like games I like playing. It all takes place in a hotel, so it is really not a click fest where you aren't sure what to do. Just visit the rooms of the girls you like and the story progresses from there. As you get to know the characters, you realize that each has a very compelling backstory, that really brings you into the story. I after you start to know the characters better, it becomes really fun to play.
- Power Vacuum - A sandbox-lite game. You are a young man with oversexed sisters, a mother, and her friends. With a dastardly grandfather that is very easy to outwit. He is more funny than threatening, so don't worry. The choices are obvious to avoid any scenes where he is involved. You just need to click around the rooms of the house to have interactions with each character. There is a room list image, and you can see where the characters are, so that helps a lot. There is a lot of repetition to get to the good parts which is annoying. But if you hold control it isn't bad. The main reason this game is on my list is that it is really, really funny, which is why I have to recomend it. Other than Spacecorps XXX, this is the only other game where I frequently laugh out loud. The scenes, though it takes a long time to get there, are very hot. If you can look past the slight sandbox-like style, it is well worth playing.
- Spacecorps XXX - Just thinking about this game makes me laugh. This game has a lot of humor, a lot. You are a country bumpkin from Ganymede that enrolls in Spacecorps, where you meet a large cast of highly sexed characters. A total culture shock. Reading the dialog from the MC as he can't believe what he is seeing, is really funny. It has lots and lots of different fetishes, sex with aliens, virtual sex with robots, gay content, many others. But don't be turned off, because it is all directed by the player. Pick choices that appeal to you, and you only see what you want. The updates are quite frequent, but short. Still there is a lot of content. A totally unique gameplay experience, and you really should try it. If you are easily offended, it might not be for you, because it is very irreverent. But I really like it a lot. Much of the humor really is laugh out loud funny, in my opinion. Not deep at all, but everything is played for laughs. Think of a super sexy Spaceballs (the movie), and you are on the right track.
The Deluca Family - I love this game. The characters are unique and compelling, the story is really good. You are a young man who has lost his memory and starts living with a family of gangsters, and you slowly move up the ranks. There is a lot of mystery of who you are and your role in everything that is happening. There is a lot of depth to each of the characters that is slowly revealed over time. Some parts of the story are unbelievably touching. I cried. I have to say, much of this game is a masterpiece. It is very slow to get to the romance, and heavily story focused, but if you like a great story, and are patient, very worth it. You owe it to yourself to play this.
Well. I hope at least some of these you haven't played, and my impressions are useful. All the games above I really love. I have about 60 more that I have played and I liked well enough to keep track of them, but I have to stop my list somewhere. Maybe I will post more later with some further recommendations if there is any interest.
