Audio? Sounds effects? Musical score? No big deal, most of us probably just run iTunes in the background, or maybe even Pandora. For most this is a viable option for MMORPG's, since unlike first person shooters, when you are the last man alive in a 5 versus 5 situation, you might want to be aware of the footsteps of the guy running up behind you, instead of your favorite heavy metal tune. Though, like the visuals, and game play, audio plays a very important role in a game.
