Guitar Hero and Rock Band are great games, but they don't really teach you how to play an instrument. Rocksmith does. This game for Xbox 360, PS 3, or PC uses the familiar method of running a rock song that you have to play along with to get points. But the twist here is that you plug a real guitar into the game system and have to learn correct fingerings to make the right chords. Play the song correctly and you'll score big!
