Insomniac's Spider-Man is a masterpiece and a hero game of this console generation not to be missed!
Spider-Man respects the IP and brings a fresh aspect to the characters, the setting and the gameplay. I feel I can't add more to what others have said. Combat is fast, fun and visually exciting. It uses the Batman Arkham series style and it just works with the hero. The world feels real, traversal is a blast and you end up feeling sleek as you swing through tiny gaps and preform maneuvers. Ultimately, the story is great! It invests you into the characters and feels well paced.
A real contender for GotY, well done Insomniac, you nailed this one.
