Dwarf Fortress is the state of the art in procedural interactive story generation. Youtube channels like kruggsmash show how great it is in that role if you actually read all the text.
But that doesn't translate well to websites, trailers or demos. It's easier to wow people with graphics.
But the narrators aren't narrators; they're just different settings for the relative frequencies of events. Dwarf Fortress is still a more robust "story generator", as the vast majority of what occurs in Rimworld is still basically random events, disconnected from prior events or context.
I guess I see what you mean, but the way they handle difficulty scaling, and the existence of quest chains, by being more fake, is closer to how stories are told, than the more 'realistic' simulation of Dwarf Fortress.
