MAG looks to be very strategic and fun for everyone. All it needs is the trohpies, for people obsessed with being the best, and the leveling system like CoD4 and CoD WaW has. I mean its things like that in which brings attention to the gamer to become the best and noticed as a complete badass. As far as lag goes, well i am pretty sure they got some big hefty servers to support many people, especially on a 256 players a game basis.
My only concern is if its all just ground war. It would be better if there were additions such as planes, cars, tanks, weaponry and such.
