realistic strategy war simulator.
"Go to that place the enemies are at, shoot some dudes and stop them from taking it away!
Also, they might have a few tanks and more than two dudes, so take some other guys with you and work as a team, okay?"
I wouldn't call it realistic or strategic, it's just a game with more variety than MW3 and the gameplay calls for teamwork as opposed to running around a map smaller than the maps in the first Call of Duty with a sniper rifle which is effective at ranges 20x greater than you will ever see because of the map boundaries just so you can kill some dudes
