So maybe you don't really learn how to play an actual guitar when playing Guitar Hero, but I did come across a game at CES that will teach you how to play the piano. Piano Wizard is a neat video game that can teach anyone how to play the piano and read music. A four-step, color-coded method paired with a stimulating video game is said to be easy enough for a 3-year-old and challenging enough for an experienced musician. The Piano Wizard can be used on both Mac and PCs.
