Yup, there's been a few listed on here already, like the works of
Omni-Waifuism and others. As far as I'm aware, one of the tags that are in the works at the moment for the site is 'AI Art'
Disclaimer: This is intended to be my thoughts on the existing problems AI art games face, not a dissertation on why AI art ought not be used.
NovelAI and Midjourney are likely to become the new whipping boy of art direction after Daz, I think. The main issues people tend to run into with using AI art are similar to using real porn videos/images. Namely, artistic consistency over the course of the game, because AI isn't intelligent and is basically playing with RNG to produce things 'close enough' to what you want, similar to how real porn games often have to play fast and loose with setting.
The other one is more unique to AI art, which is the tendency for censorship of porn by... drawing a blank on the word. Companies like paypal, and ratings boards, and lobbying groups. We saw this with onlyfans, and pornhub, and tumblr. As this is a porn game site, games using AI that are unable to produce NSFW images will be at a distinct disadvantage.
This has another, concurrent problem. AI has biases caused by its training data, which is an inescapable fact of teaching an AI to associate words together, or words to images. It will tend to associate certain words with certain things, in ways similar to a human, so an AI's art direction is biased
by design by existing real world beliefs, as part of its training process. An example of this is NovelAI. NovelAI's image generation is heavily biased towards producing anime women in a 2015-2020 art style. An example of a problem with this would be faceless dude bias. Men are so often cropped out of images made by humans, or represented as just a penis, that if you
want a man in a sexual picture, it is incredibly difficult to make NovelAI's imagen produce that. So if you want something atypical... be aware that you are working uphill against a
distilled form of human social biases.
