I've played America's Army in the past but my computers video card and mobo fried so I am building a new computer soon.
it's a good game, very realistic. I don't like America's Army for the XBOX 360 though, it's nothing like the original game for the PC where you actually have to take classes and stuff like medical school or parachuting and using the sights.
I haven't played it in a while but yeah it's a fun game.
I also have call of duty 4 for the xbox 360, fun game, I beat it in a day in 8 hours.
