As others have stated, it's not as polished as Guitar Hero, but that doesn't hinder the game play. It's just as much fun PLUS better music!! The only drawback for me is that it doesn't run on a 64bit Windows OS. I'd love to see an update that lets it work on 64bit, but until then I have enough parts to make a dedicated computer just for this. Also, having a 61" tv to play it on isn't bad at all. :)Get more detail about Guitar Praise By Digital Praise.
