Just hope arma will get more stable and don't have quite the terrible AI to play with.. ruins missions (should never happend in a game where AI ruins it for you, can be more secure else nope..) The Large Scale is the best thing though and the landscape.
Else for those who want some casual fun audiosurf, Skulls of shogun:
Fistful of Frags
Free to play game but quite fun!
One Finger Death Punch
Cheap but fun game
another cheap one fun split screen.
Rock Of Ages
