Implying anyone that just doesn't like this game is a Disgruntled hater nerd, makes me think it is you who should get a life.
That being said, apart from a few variations with how killstreaks work, I haven't found this game very amazing, I will still play it, because MW2 will be deserted as off this week mostly, though this game is only really a Sequel in Single-player story-wise, and moreso just some DLC multi-player-wise. Anyway, off to go UMP some people in the face.
