So, dwarf fortress?
It would also be nice if it didn't feel so random, like masterwork obsidian battleaxes that menace with spikes of orthoclase. Or 6 armed bat winged llamas that spit bile.
Rimworld tries to tackle the story part, but ends up being too dramatic instead.
There was a game called Firan MUX, which did an excellent job of generating families and backgrounds for each character and I would spend hours on that.
