God of War 3 will not have MP, and truthfully, it doesn't need it as it's sold millions of copies without the feature. BTW, there really isn't much you could do in terms of MP when it comes to the game. Story driven games like Uncharted 2, Halo, etc all work because they share the same weapons and the hit detection system for the characters aren't that different. Now how are you going to have Kratos, with hundreds of different moves, at least five 5 weapons, etc fight a giant cyclops that only weilds a club and has like four or 5 moves? Where is the balance needed for MP?
