No one will be disapointed with this sequel at all, is better than the first
More than improvements, this game is an evolution of what we already saw of God Of War.
Without spoiling anything Kratos is again in a quest for vengance, and "he must do something that no mortal, god or titan have ever done, change his fate", and that's awesome.
The grafics are breath-taking, there are moments you can see the enormous environment and horizons and Kratos looks like a tiny lil man, and I'm tell you, that's an excellent photography direction.
The trade-mark finishing sequences are the greattes in this game, you can do very violent, horrible, nasty, incredible things to your enemiges. the game comes with a second disc (a DVD) with extras: making of, interviews with the voice cast, pictures, etc.
This is a must have game, I'm so waiting for God of War III
