From what I've read about Fable, I honestly only think this would be an interesting game if it were designed for multiplayer, in other words, a single-player game designed to be played on the internet. The idea of all my choices effecting a static environment really has little appeal to me, but if real people were playing in a game world where everyone's choices effected it and everyone was forced to be in character (just offer a dialogue system and eliminate the chat function), THAT would be cool. I'm surprised that no developer has done anything like that yet. I guess from a game design standpoint it would be extremely complicated.
