I recently chatted with some game developer friends about this. You just write backstories for each of the characters, you can even have them interact with one another easily. The issue currently is the length of that characters story, but definitely see some interesting stuff happening. I mean you could just take some short-term lived characters and that would work pretty well. Like an enemy you have to defeat. Procedurally visual, with a randomized backstory and traits all from ChatGPT, then can take in small details, but then each encounter would be a bit less repeating.
