'Great' and 'AI-generated' are not two adjectives that usually collate in any field, let alone video games. AI-generated video has been advancing at lightning speed, as demonstrated by the recent release of Sora 2 and the Sora social media app, but it's still a long way from being able to make a movie. Video games are more complicated, requiring real-time decision-making and functional constraints. A half-decent playable AI video game within a year sounds far fetched, let alone a great one.
