In Fable 2, like Fable 1, it kinda focuses on combat and alot of action. In Fable 2 Lionhead Studios wanted to make the game more social, but Fable 3 is all about that. Sure, Fable 3 is fun, but it's kinda a sit back and relax game. But it is your personal game interest.
Fable 2= alot of action
Fable 3=communication and better for co-op
Like everyone else said. wait about four days and it will still say that you have it, but it will also say you have the next game in your Q, that just means your old game hasn't gone through the system.
