Chat GPT + Voice Synth will not only allow for the story lines to be written but for the voice work to be done.

I was really disappointed listening to Tod Howard and how Bethesda felt that someone realizing part way through a play though that they really wanted to play a different character, and treated starting over as having failed the player. I mean with that sort of attitude no wonder the games have been getting blander and blander.

Now think of a different future where all the interlocking storylines is all worked out ahead of time by a LLM. Where having everything be based on your current skills and previous actions 'behind the scenes'

so instead of blending things to a grey mush to 'disappoint' no one, instead you can have vibrant different adventures through the same land each time you play.
