Rocksmith.
I was given an electric guitar for my birthday with this 'game' and have actually been learning how to play
Gotta go with this. You can get a real guitar for not much more than the cost of a guitar hero guitar, Rocksmith is far more complete and comprehesive than any guitar hero or rock band could ever be, AND when you can finally master those songs on expert, you'll actually have a half-way worthwhile talent.
I've been playing guitar for over 10 years and Rocksmith is still very useful to me, also been playing it with a friend of mine completely new to it, and he's making faster progress than i ever did. It's also a solid, enjoyable video game to boot.
