I'm not surprise at all. This game is absolutely gorgeous. I've played it 3 times already and I'm still going on in chapters to see if I didn't miss a thing.
The atmosphere is great. As another mentioned, the animation is nice and well done as everything else anyway. Some pointed out that the AI was not good but it's because they didn't understand the concept of LIGHT and SHADOW because the game is meant to use it for the AI in order to spot you. In shadow even if you're in front of someone he's not seeing you. Right because it's suppose to be too dark to see and the game was make with this fact in mine
IGN gave a 7.7 for the game. Many comments were through at them blaming them that their review sucks hard and I believe it. This game is a 9.5+
