Resistance 3,Heavy Rain, Uncharted 2, Little Big Planet, The Walking Dead. I did not expect much from these games until i played them.
My biggest upset this Gen has to be Spec Ops: The line. Amazing amazing amazing game. The story, the twists, the characters, even the gameplay (since I had heard that it was the weakest part of the game) It all worked perfectly to simply blow my mind. I recommend it to all story driven, FPS lovers.
