Modern warfare 2, hands down the best multiplay game for the xbox 360 bye far. It is the most played game online right now. Personally, I do not like Gears of War 2. The story line isn't as catching as other games. Bad Company 2 is supposed to be like MAG for the playstation 3. 256 people in one match?... MAG is awesome. So I would get it Modern Warfare 2 and Bad Company 2. The story behind the Call of Duty: Modern Warfare series is amazing. The second one reminded me of the movie Red Dawn. Its an older movie where Russia invades America and a group of teens who call them selves the "Wolverines" fight back. And Modern Warfare 2 multiplayer is just THAT cool.
