The AI stuff tends has big problems with consistency, on top of being horrible ethically. The assets used to create it are stolen from people without their consent. It's merely easy to justify because it obfuscates the fact beneath so many layers of separation. Nobody can really stop you from doing it for fun, that's on you, but to actually suggest it should be used seriously to replace the actual artist doing the work because you just want your porn game is ridiculous.
Plus, it's not copyrightable, which brings up a bunch of legal concerns regarding the IP.
All the games on here that use AI can have their images swiped wholesale by another dev and they legally can't do shit about it.
So, it's self sabotaging, its quality is dubious, its got a host of ethical problems, and its insulting to suggest to an artist who enjoys making art to just let the machine do it for them. And for what? Just so you can get a sea of samey yet inconsistent images of your favorite characters fucking? I'm not gonna take you serious bro, that shit is buns
