1. Gears of War 2 "Mad World"
There was no guitar shredding, screaming or rapping. Only the soft crooning of Gary Jules' "Mad World" as we saw Marcus Fenix in the heat of battle. This commercial not only showed how incredible Gears of War was but it also connected on an emotional level when we saw Marcus go up against what looked like an impossible boss fight. Damn you Cliffy B, shut up and take our money!
