Procedural generation has been pretty popular in games and I could see continuous AI generation becoming a thing in the near future. Always online required, and constantly scraping the internet to compile new levels based on Mass Effect style dialogue options/input.
Not any of the other games that have used that system, though. Just Mass Effect, because it's GOAT.
Having something else to customize would be alright, but most peoples' results are going to look AI generated anyway.
