Yeah, ultimately a lof of devs are trying to make “story generators” relying on the user’s imagination to fill in the blanks, hence rimworld is so popular.
There’s a business/technical model where “local” llms would kinda work for this too, if you set it up like the Kobold Horde. So the dev hosts a few GPU instances for GPUs that can’t handle the local LLM, but users with beefy PCs also generate responses for other users (optionally, with a low priority) in a self hosted horde.
