There are lots of them, but they're mostly indie games.
Sorry to revive a slightly old thread, but do you have some recommendations for good shock-clones?
If you say Bioshock I will explode with the force of a thousand suns.
Also, to get back on topic, AI by it's very nature can only produce generic garbage. It's not capable of making anything new, all it can do is combine existing components in a new way. This can work for making artworks because there's a lot of wiggle room and leeway where our eyes don't really notice small imperfections or nonsensical combinations (we do notice when characters have too many fingers, though), but for something as complex as a videogame, at best you'll get an unfun and unbalanced mess that hasn't undergone the required testing and refinement that's literally impossible with AI (and always will be because of the fundamental way AI is designed), or at worst you'll get something that's literally unplayable because the AI has no concept of coherent game design so you will get nonesense that literally can't be completed. It can only emulate the style of input with it's output, it can't make reasoned judgements or understand the implications of what it's doing, which is required for designing a game.
This is why I don't like to call it "AI". AI is a total misnomer. There's nothing intelligent about it. Even Machine Learning is a bit of a stretch. All it's doing is analysing data (in a contextless way, I might add) and then emulating that data through successive iterations. Don't put any faith in AI, all it can produce is slop. The fad will die out in a few years, and then everything will go back to normal. It will have some uses in niche areas where accuracy and context aren't as important, like image touch-ups, but I giggle endlessly when I hear people talk about how "AI will be writing code in a few years". Humans can't even write code most of the time, and we expect machines to do it for us?
