I don't need to explain to you how Guitar Hero works, so I'll skip writing about that. There is tons of old and new Metallica stuff (and thats good for everyone - if your more of an oldschool fan or a newer style fan)! My only complaint is that for some strange reason there is ALLOT of NON-Metallica songs in the game (and I'm not talkin' about the covers they've done - they are here too but they are being sung by the actual artist and NOT Metallica), they just have no place in this game. But other than that; all Metallica fans (old and new) and even non-Metallica fans will enjoy this game! RENT IT (...or better yet: BUY IT!)!
