Only thing I could think is like Wild Life / Carnal Instinct but that's tied to having furry stuff which might not be your jam. Also eh as games imo, alright scene makers / viewers though.
They can, sometimes though people just string a few frames together and call it animation in the VNs, which doesn't hurt, but isn't really an improvement.
Yeah one of those items you wanna have a decision on early on, I wouldn't have known it was a strong sticking point for people like NTR before this thread though!
Can be hot, shouldn't be a surprise in game, clearly tagged. Can't see complaints if the game is based around it. I haven't seen devs cater to this exclusively like they have to other fetishes that weren't originally planned, but maybe I've just been unaware.
Karryn's Prison with a built in pregmod / filling out the medical center / more corruption options. Know it would be a big art thing but better than the current DLC's coming out imo, Karryn was already stacked.
Excited to try this when done, think I'll wait for this. Was lucky enough to only play Once in a Lifetime when it was done, and this one seems well liked too.
It becomes a scaling problem with too many, keep it smaller you can develop the chars well as well as give player choices on who enters. Larger just more overhead, make them unique, consider interplay, and if you want to give choice on who enters, have to do scene variants etc.
