@jeffbordonaro, here are the differences in game play for you (From CoD 2): COD 3 - Improved Classes in matchmaking MW - Sprint, Perks, Killstreaks and Ghillie suits WAW - Vehicles, Flamethrowers, Zombies and Co-op MW2 - Heartbeat sensors, more (unbalanced) perks plus Glitches!!! BO - Well, I have yet to find out... but I think you may have got the point
