I think the way video game devs/people are (from what I can see from outside) they are well poised to realize someone making an LLM or a finetune or whatever you want to call it – that produces master level dialogue/stories/whatever is (will be) a skill just like storytelling/writing is.
If I were a JRR Tolkien or Herbert with a universe in my mind, it would be so much more pleasing to make an engine that generates anything from that world that to just write out a few stories from it.
100% the future. Like has anyone put all the billion pages of lore from TES into a GPT finetune? Surely that would make better dialogue than HALT! for the 900000000 time right?
