Hmm, I'd say that the god I'd love to kill would be Zeus, since I consider him one of the main gods, who needs to die in the worst possible way, aside from him, I'd branch it off into Titans and see how Cronos is killed D:
I already know that Kratos will die, since he dies on the first one, and these are just the events leading up to it. The thing I'd like to know though, is as KeyStyle asked, about his brother, what will happen to him? I mean, Santa Monica said it won't be the last one, does this mean we might continue the story through his brothers eyes? o.O
My favourite enemies would just be the normal soldiers, as you can cut through a few dozen of them without getting hurt, and all you see is blood splatsand corpses flying all over the place, I like that, it's great. It's even better when you can grab one of them and charge through a crowd knocking everyone all over the place.
The OH MY GOD OF WAR III theme sucks because it isn't actually God of War III, but a theme, this is disappointing, and I demand the real game. Right. Now.
