In the two years since it was first released, Guitar Hero has become something of a cultural phenomenon. It has inspired T-shirts, bands, South Park parodies, and the inevitable "is tomorrow's Clapton playing Guitar Hero now?" questions. (Get with the times you old fogeys! Clapton????).
Its popularity partly explains the shift away from PC gaming -- a scene which has eroded so much that Microsoft has set up a taskforce to try and save it. Quite ironic, then, that Guitar Hero is coming to the platform it's helping to destroy.
Is this the game that will help save the ailing PC, and help make the platform social again?
