Just making a post giving a general breakdown of whats in the game, what to expect, the worst parts about it, and the best. I haven't explored all the options as far as like the prologue stuff (didn't pick other ways to have lost the MC's virginity, nor did I do a virgin run).
First and foremost: Ironically with a game all about goblins, there isn't any real NTR content. Which is to say: female characters do not mention in most cases having a boyfriend/husband. If they do they are an ex, or they are a character that will be given no sprite detail, no CG art, and ultimately barely are relevant in 99% of the game. Some female characters including the MC will degrade human cocks, or past lovers cocks, and in one particular part of the game you can technically miss; two sex therapists (not really but you will understand if you get to the scenes) will sort of compete against each other, and one will one ask the MC who she prefers. But make no mistake, there are no feelings in this context, literally just people using other people to get their jimmies rustled.
Choices at the beginning: As I said I haven't tried any choices, but ultimately they do little outside impact your sex stat card which you can see understatus. Obviously picking the virgin option does allow people who love that fantasy to experience once.
Fighting: This is both oddly a great, but also arguably the worst part of the game in my opinion. It's great, because alot of great CG scenes, and writing occur as your character loses "trades". Trades in this case being, if you pick rock, and they pick paper, you lose the trade. The translation for some of the hints for trades seem counter intuitive. An example: mid/late game there is a trade that has a high chance of occurring if you had recently won a trade and hit an enemy. The way this dialogue is written, suggests they are running away scared. If you try to pick the option where you charge up an attack, because you might feel like your safe, this option is sometimes correct, and other times it is sometimes very wrong. Instead sometimes you need to pick the counter option even though the words as printed are exactly the same with no other indicators I notice. I did technically notice, the first time you see that message, and you haven't hit them recently, then the charged attack will be correct. And then you sometimes see it come up again, which means you should do the counter, as the enemy is actually planning to rush you, and will punish you for a 2nd charge attack. This isn't 100% consistent, but it was the most consistent pattern I saw for enemies later game, and against a particularly bullshit endish boss.
Fighting pt 2: The good things with fighting, is every time you lose a trade, you get a alittle CG with some dialogue, usually referencing a character losing armor somehow. Outside of very special fights, if you are fully armored up, it will take 4-5 losses, and then you have to lose a trade that final time, to force the defeat CG, and then a follow up CG of what the goblin wants to do with you. Further if you are trying to just force scenes, there is always a button on the fight screen to blow off your armor, so you can start at 0 armor for a fight. Similarily, you can gain all of your armor from a spell, when not in combat, and i has unlimited uses and cool down.
Content: Overall the game for me took alittle over 5 ish hours, but I was screwing around, and forcing multiple loses each time, and for each major boss fight to see the different options. In general most content for most goblins(there are over 5-6 goblin types, with the most general original one having some unique gangbang scenes, or unique post game scenes if you get the horny ending) involves one art piece for stripping your armor, and molesting a part of the MC's armor that is stripped. A defeat cg, where they finally claim the MC, an after credits victory for the goblin after submitting you, and each of these scenes, has a general variation based on your submissivness, if you've cum from a goblin yet, if you've had a goblin baby, or if you have been claimed by that goblin type more than once/twice. Don't be mistaken, most of the art is the same (so each goblin only has about 5-7 cg's dedicated to its type), but the text can vary wildly based on the above factors.
Availability/accessibility of content: At the end of each main chapter, you get access in the guild to a glowing orb, that orb will save all the scenes you have witnessed to that point, so you can always replay them. This includes the battles, as well as the defeats, and extra defeats after the fact. Beating the game gives you just about all of them. The only ones that don't seem to show up afaik, are the special scenes that are part of the post game for the horny ending. There are about 4-5 unique CG's that only happen in the guild hall. But for people looking to watch 99% of what the game has to offer, you can use some of the saves posted in the threads here, and you should basically have everything if you don't want to fuck around with the terrible combat.
Characters: Overall the characters are pretty meh, with most of the energy going into the MC, MC's rival, and the guild receptionist. Do know other npc's will have changed dialogue based on your actions, or you completing an area, but outside of 4 occurences, doing those interactions usually just leads to comedy dialogue, and 1 implied blackmail blowjob. However, while you spend 90% of the game playing the MC, MC's rival can be played briefly, and has some custom CG's, and the receptionist isn't playable, but has 1 personal scene, and one post game CG with the horny ending. Definitely feels like a saberface situation though, in that they all wear differen't outfits, have differen't weapons, and so on, but their faces and general body type is the same.
Overall: Honestly a cheap game, with a sort of lazy approach to combat, but imo it hits quite a bit above it's weight in enjoyment at least for me. While the characters aren't detailed works of art: if you like big tits, and big asses, and don't mind little green men being in 98% of the porn art for the game, this is definitely worth a look/try.
Negatives: Biggest negative was already talked about, but it's the combat. Other negatives is it probably isn't as expansive for fetishes or turns on for alot of people. By no means is it shallow, but if you wanted a petite girl, or someone who isn't white as snow, or anal action, this game just doesn't have it.
Tips: You can technically farm alot of money early enough to get the best purchasable in the game, which is an attack that replaces your standard attack. This attack instead is guaranteed to wipe out any non boss enemies. However, it isn't as strong as it sounds, as unless you pick a fight with an actual sprite, or its scripted, you can run from all the random pokemon like encounters you get for being in the tall grass. Further, if you forget to take this power off before a scripted/boss fight, it's actually useless, and you lose effectively one of your tools for beating the AI's rock/paper/scissor options.
Tip#2: Try to get pregnant. If you do you actually cut out some really decent content, and ironically being pregnant with a goblin leads to the only real human/human scenes in the game. If you're worried about getting the horny ending, at the end of the game you can spend money on an item that will reduce your submissivness. Getting it below 100, and not failing in the final act means you get the "good" ending.
Hope this helps anyone trying to see if this is an NTR game (It's not), if it has anything to offer, and also just giving you an idea of the content if you just choose to download and then get someone else's save.
