For those who think that the concept of Guitar Hero is awesome, but that listening to those bands damns you to hell, or just want to rock out to some wholesome Christian rock, we have Guitar Praise, the PC game (and included guitar peripheral) that lets you rock out on fake guitar to dc talk, Caedmon's Call, and Petra (among others). Sure to be a hit at your local church this fall.
