Modern Warfare 2 was a fairly decent game. Obviously, anything with a build-up remotely as big as the one for this game will disappoint many. I wouldn't say it was terrible, but I never saw how so many people could prestige over and over and over again.
I'm approximately level fifty, or something, and I'm getting kind of sick of it, to be honest. My account is Silver at this stage, so I can't play online, anyway. I'm thinking about trading my game in, though. The only thing really stopping me is my sister, who irrationally loves the game.
