Guitar Hero III is awesome for mainly two reasons. The first one is that you get to be a guitar playing demigod. Depending on your experience and skills, you can well be the Zeus of fake guitar players. The second thing that makes Guitar Hero III great is that it lets you take on all those songs you heard on the radio and make them your own, creating an emotional bond to the music.

Now, there is another reason to think of Guitar Hero as a pinnacle of game development - the fact that it makes people think of the Devil, aka Satan the Dark Lord, rather than the music.

Songwriter Charlie Daniels, the author of the song "The Devil Went Down to Georgia" that is featured in Guitar Hero, has stated that he is very upset with the fact that the player has to compete against the Devil himself while beating that particular song. He says: "I want any of you parents out there whose children have this game to know that I did not grant these people my permission to pervert my song and am disgusted with the result."
Apparently, he doesn't really get the fact that Guitar Hero is a game and the Devil is just a visual representation with no theological value, and with little to no impact on the sensibilities of the player. After all, the game is about playing music, not about fighting the Evil forces of the world.

The song creator went on to say that he "would never grant permission for some company to create a video game version of a song I wrote in which the devil wins a contest and I'm sorely disappointed with the company who owns the copyright for not policing the situation." But apparently the rights to the song are not even his anymore, so he has no legal recourse to force the song out of Guitar Hero.

The only relevant comment that I can offer is that Guitar Hero should have featured "Sympathy for the Devil" as the track on which you need to take on Satan himself. And the Rolling Stones version no less. I suspect they wouldn't really mind.
