Should I get Guitar Hero 3 or MP3 AND SMG? I know that both MP3 and SMG are better then GH3 but I'm a huge rock fan.... PLUS, I'm worried that after I beat MP3 and SMG, I won't want to play them again. While Gh3 seems like a game that'll never get boring. ALSO, if I get GH3, I have to wait until Jan. 21 for a shipment to come, and that'll probably be sent back another 7 days if I can't make up my mind. so...putting that into consideration...which should i get?
