My only complain is the lack of character creator, I was looking for that.
That being said, the game is indeed incredible. It gives a pretty bad impression at first, especially when FPS or physics don't respond well, but once you got past that...oh man, OH MAN! The freedom! The tension when you're ambushed by a horde! Checking every house, every gas station to gather some snacks and coffee! IT'S JUST AWESOME!
I've never feel so awesome by running down some random road checking the enviroment, seriously.
