For me Fable II stomps all over the original. The world in the original is far too small for my liking, and Fable II is more open. That combined with my dog, which is probably one of the best design choices I've seen in awhile, makes it a no brainer for me to choose Fable II over the first game, put it right behind the Mass Effect series as my favorite game this gen, and also be super pumped for Fable III.
