If you're an video game fan and an avid piano player sooner or later you're going to want to play your favorite game music.  The problem is that (with the exception of certain Japanese RPG soundtracks) game developers and publishers aren't printing up books of sheet music to teach you how to play the theme from Super Mario Bros. or the haunting Protoman Theme from Mega Man 3.  That's where the devoted fans on the Internet step in.  Over at the simply named Video Game Sheet Music page one piano enthusiast has transcribed a number of classic game tunes in both PDF and NWC formats.  As a piano player myself I can vouch for the overall accuracy of these transcriptions.  All your favorites are there: Castlevania, Mega Man, Metroid, The Legend of Zelda, Faxanadu, and more.  Download 'em, learn 'em, impress your friends with 'em.  If your friends are impressed by game music on a piano, that is.  Otherwise you should probably keep these to yourself.
