I have Modern Warfare 2 for the PS3, I am currently First Pretige level 70. I am absolutely addicted to this game. What system do you play on? The gameplay on MW2 is amazing, even though after a while I get bored, so I got play CoD4. But, the game is very realistic, and much more elaborate than the previous CoD games.
