I think it's like comparing apples and oranges. I thought Fallout 3 was a shooter? Where Fable 2 is RPG. Don't know much about fallout but Fable 2 is so fun, funny and awesome!!
Well, it's really hard to compare, since they aren't really similar. But I'm going to go with Fallout 3, it looks amazing, the gameplay is awesome, and it's from Bethesda!
I agree with Schnazzy. They are two very different games, hard to compare with similarities to connect them. Fable 2 seems like a pretty nice game, but Fallout is definently better. The plot of Fallout3 is complicated and realistic, and Fallout has alot of components put into one game, making it a fun and great game.
