so i just bought rock band (it was released recently here) and its awesome. me and my friends have made it up to act 10 twice but we dont have a memory card and some funny person in our flat is turning the playstation off. we really just want to unlock hysteria by muse, but we dont know how far we have to go to unlock it, its annoying, but in a fun way anyway, since i bought rockband 2 sets of my friends have been looking into buying guitar hero 4 saying its way better, even though it will cost them twice as much. they say the song list is way better (this doesnt matter to me, i pretty much just bought it for hysteria) (i think you pay more for more wirelessness, an extra drum piece and better songs) despite them being so similar, have you played these games? what is your verdict
