Battlefield 2 - the Foley sounds, such as flipping the auto / semi auto switch on a M-16, are amazing - as are the nature sounds that permeate the background - birds, water running, then the sounds of war - far off machine gun fire, helis swarming overhead, people screaming for medics.... its crazy.
Only problem with the game.... its an absolute system hog. I had to go buy a new ATI X850 graphics card just to play it on my P4 2.8 / 2GB RAM system. Worth it
