Imagine if townsfolk could have realistic conversations and interactions like bartering over goods, etc. Nothing major or plot-dependent, obviously. Just something more natural than a handful of repeated, scripted and prerecorded phrases.

There's already a in-development Skyrim mod for that. Many sandbox games have mods for exactly this.

I haven't tried the Skyrim one though; haven't been in the Skyrim scene for awhile. And TBH, some of the mods use pretty sad or sloppy LLMs by default.
