TiTS and CoC2 have some, well, call me basic but I deem that stuff extreme fetishes. Every npc is either just obese or extremely buff, has 6 tits or 2 dicks on top of being a lizard covered in hair and wings, it's just too much in my opinion. I have not played Liliths throne and Abyss Diver Interactive yet, but I'll put this here so I can hopefully get something more out of you >:) I have played Lust Doll before, it was a nice experience but quite closed and I had found myself looking for a walkthrough on how to progress the game quite often. This project looks rather promising as of right now aswell. But yeah, if you have any, literally any more suggestions, I'd be pleased to hear them.
Dont worry Im always on the look out too, but thats about it for all I know, hence making this. Theres another called Rogschard, I could never get into it. And Strive for Power, fun again for a bit but never that much into it, though I heard others love it/have big modding communities.
Oh and Broken Dream Correctional Centre, again couldn't get into it, but really cool animation system.
Enjoy the research ;)
