Is not even close for videogames yet. People were jumping on AI movies for example, which are less complex, since they don't have players' input or commands, and as of right now you are getting 60 secs of generated video. The amount of resources required for a full say 90 mins is crazy. Just to get an idea, Disney spent 3-4k per second of CGI for The Marvels.
So don't hold your breath for AI games until 2 more gens maybe. They might help with cutscenes generation but a fully AI developed game won't happen until 2040.
