Part of what I really liked about it is that your choices have consequences in the rest of the game. And sometimes you can’t trust the person requesting that you do a quest. (Versus the typical trope of them being infallible and leading you down the right path for successful game completion).
When I finished the game, I was a bit sad that it was over–but quite happy that some downloadable content showed up soon after (at a price, of course).
Right now, the XBox store has the DLC for Fable III for free, in addition to a free dog pack (you can change the breed of your dog with it).
I just got the dog breed set, and I already had Traitor’s Keep.
