Maybe, but would that improve the gameplay experience? In my opinion, if you can generate a million unique creatures or a billion unique creatures doesn’t matter all too much, because I can’t imagine that the average player will ever see more than maybe a thousand. Even as it already exists, it’s pretty much impossible for a player to experience the full breadth of No Man’s Sky’s potential. It would definitely be an impressive technological accomplishment, but not one that I think offers anything substantial to a player.

Personally, I think AI’s use in games is better-suited toward NPC dialog. There’ve been some tech demos showing this, and it still needs a lot of work, but shows a ton of promise. I think that given the right parameters and limitations, there’s more potential for gaming on the LLM-side of AI than anything else. I’ve not played NMS since launch, but I don’t think the current version has much in the way of character development, but that could be something that a sequel could make use of AI for in a sequel, I think.
