Why do you keep lying? THERE IS NO REAL PLAYING OF A GUITAR in Power Gig! I bought the game at Best Buy accidentally the day after Christmas. Unlocked all of the songs so my fiancee could play Dave Matthews. Bought a guitar amp and patch cord so I could actually play it. Again, do not listen to this guy.
I do disagree that PowerGig is as bad as the reviews it received. I have played Rock Band and Guitar Hero and using the controller will knock you down a level, but that should be expected. It does motivate me at least to try harder. My fiancee is scared to move to a level she will fail at more times than not and enjoys getting 100% on easier levels.
What 'does it do that it claims' that you believe? Dismissing a review when you have no freaking clue what the gameplay is like makes me dismiss anything you ever say as total bullshit.
