Modern setting with no fantasy, SF, powers or anything like that. Basic 100% realistic except how horny the female NPCs are for MC (or how slutty the female MC is.) Nothing weird and NOT cartoonish. As realistic looking as possible. Uncanny valley isn't a thing for me.
There are very few of them, bimbofication of an already female character (ideally the MC), and slow corruption (sadly it takes a long time for those games to get developed to the good stuff).
I don't take XXX games seriously. The vast majority of developers do not have a noticeable literary talent to create an interesting story, the same occasional cases when you get something relatively interesting, is good only for stress relief after work. Not a single completed game I've never gone through a second time..... I guess I'm too old for all that.
Am I alone in liking some of these games for the mechanics? Usually enjoy the management games. When I can find an adult arpg I think it'll be over for me
