Ok, so yesterday, I got an Xbox 360, and two games, Ghost Recon Advanced Warfighter, and Call of Duty 2. I am hoping to get Xbox live soon, but I want a game I can play with my friends and family, two player, without having to fight each other. I've heard good and bad about this game, and I was wondering, if I got it, is the two player game worth it? Plus, when I get Xbox live, is that worth it? And what's the singleplayer campaign like, plus, can you play two player with the campaign?

Please tell me the good and bad about this game
Thanks
