Haha that's the typical arguement MW:2 Fanboys use when they try and justify how bad their beloved game was. The fact that you point out whichever team was hosting had a better connection makes the game bad to begin with. The MW:2 Matchmaking system ripped apart any form of community the game had. If you tried teaming up with friends or clans you were lucky to get half of them in the game or you would DC as soon as you logged on. Than due to no dedicated servers the game is full of cheaters, hackers, stad padders and just typical FPS kiddie assholes. The single player was absolute crap. I do though give IW a pat on the back for making the air port level which is imo one of the best game levels ever created in terms of just plain shock value and setting up the storyline. Once that level was over it was all down hill from there.
You're saying it's the best first person shooter ever made? You obviously just started gaming and only have a XBox 360 since you havn't played Half Life, Half Life 2 (The best FPS ever created), System Shock 1,2, Return to Castle Wolfenstein, Turok, Golden Eye, No one lives forever, CS:S, Perfect Dark, Dues Ex (Arguebly one of the best games ever created), Halo 1, and Quake 2.
