I could see somewhat of a way around this. Feed AI hours of gameplay footage of a completed gameplay run and have it review it, then have it try to recreate the game to the best of its ability. Won't be perfect, but could work.
Have llm do actual playing, do a speedrun uncovering every little detail (maybe apart from parallel story lines but they could hallucinate branches).
Probably will consume gazillion compute but now seems like sky is the limit, on a good compute day at least
I don’t know why paying AI companies is better than paying devs for their actual work. Pretty sure this won’t work though outside of the most cookie cutter Unreal Engine games etc.
