Quoted from jake35:Gunsnroses....
While certainly a fun game, I don't think it comes close to Metallica. I own both, and owned AC/DC for a couple of years. I played AC/DC a little more than GnR, but play Metallica 10x more than that.
I have only played a couple of games of AS, and I couldn't hear it at all. I am hoping to find one to play. Beating Metallica will be a tall order though. It really is a great pin.
