Personally, I'd rather not have a new Kind of Fighters or Metal Slug or whatever if any part of it was AI generated/assisted. This might sound like hyperbole but I assure you it is not. You know that feeling when you visit the Sistine Chapel (or some such place), you look up at that magnificent ceiling and think "how did one person, one human being who had the same starting point as myself produce something so magnificent!" This is somewhat similar to how I feel when playing an SNK game. The graphics and gameplay being produced by another person's hard work is all part of the experience.
Using AI for any part of a new SNK game will take away from the experience (significantly). Even if it is a case of -human draws one frame of animation and the AI extrapolates the rest- it might save time, money and make the venture profitable and hence make the venture happen in the first place - it would not be worth it because it is not a real SNK game. It's a lame ass AI piece of crap. Even if it looks 1:1 with a 'real' SNK game there will be some uncanny valley vibe to it. One might argue that it would be fine to use AI in something like testing, one could argue that people don't see, feel or hear testing. But I'd argue against that too.
Code written by AI looks 'fake'. It's hard to describe, the code just looks too perfect, it is 'synthetic' looking. If a game is tested by AI it would just be perfect, and completely bug free. But as we all know, bugs/glitches are part of the gaming experience and even at times evolve into real gameplay (think Street Fighter 2's combo system).
