I learnt about this game from this site, but I don't know how widely known it is; Cult: Awakening of the Old Ones [http://cultrl.wordpress.com/about/].
The game is a (currently pre-alpha) text based roguelike that aims to procedurally generate a world, it's history, it's creatures, gods, the civilizations, their nations, their languages, their religions... and other things. I don't know if there is an overarching plotline, but still the amount of stuff that's just created from scratch to create a single playthrough sounds amazing and it's... sort of like what Yahtzee is suggesting, but not really but sort of, in some ways. You can download an early version of it's world generator from the site if anyone is interested.
