This is like GTP 2 of World Gen.

10 years from now we might have games that generate entire worlds based on the unique story line that's customized for each playthrough. Maybe even endless stories.

Baldur's Gate 5 is going to be memorable!

The Elder's Scrolls could use this + Radiant AI for some neat quests when it improves.

Game studios are probably going to explore this in dungeon generators first where if things go wrong with the generation, not much is lost. Just exit and generate another.
