I gave up on MW2 after getting killed by way to many friends with their 15 foot tactical knife lunge of forget the what. And then theres the virtual insta-kill SMGs. Not to mention the dual models that have no loving place in a modern combat game, over-powered pieces of stuff. The air support almost ruins it too. Every 3 seconds a god damn harrier/apache/blackhawke/missile is raining hell down on 16 people in a pretty small map. The nuke is just a terrible idea. AC-130s are way to overpowered on open maps. Chopper gunner is the same way. Harriers are almost always hovering around in the sky. Campers are amidst in almost every match, hiding in their corners usually with shotguns and the like waiting for you to pass by.
Cod4 for the loving win.
