Procedurally generated worlds are one thing but imagine exploring an endless world where you can talk to every NPC and never have the same conversation twice
That said, though, I can definitely see a use for making the world feel more alive. Watch_Dogs: Legion put a lot of effort into having tons of voiced NPCs with interesting conversations and phone calls, but you could go even further by having an LLM generate text to be read by an AI TTS system.
These days, AMD has low power SoCs that include an NPU, and Nvidia seems to have just remembered that the consumer market exists. I’m sure next gen (after this one) consoles will do something with that hardware.
In a modern game, the crisis was scripted, and then you’ll get a scripted followup, or you’ll get a few scripted answers you can choose from, and half the challenge is figuring out which ones the game designers think are the good ones and which ones are supposed to kill you.
Now let’s imagine the crisis arose organically because you got yourself into a bad situation, and the options from your crew make sense in context, and maybe none of them will save you or maybe some will and you can’t just figure out which ones the game designers thought were good.
Basically, tabletop roleplaying with a good group and a good DM, but as a solo game with fancy graphics and all that.
I’d pay good money for that sort of thing, and it’s not something that can be built yet but which sufficiently good AI tech can enable (or maybe it’s now possible but only very recently).
