You should have researched it a little more before you made the purchase. You aren't going to get COD or Halo like experiences from a game developed with the U.S. Army. There are countless games out there that provide that kind of experience, this is one of the few that try to provide a realistic feeling for those that want it. Variety is a good thing, and that is what this game is amongst all the countless mainstream FPS shoot clones. Because of this, you can stick to COD4 for your unrealistic experience, and those that want an extremely realistic game can play AATS.
Future advise. You might want to pass on Operation Flashpoint, Armed Assualt, Ground Branch, Soldier of Fortune, and Rogue Warrior.
