I bought this game to play with my family, with two guitars. After installing it I realized that, unlike literally every other Guitar Hero game ever made, there is no way to unlock the songs other than playing through the entire game by myself... not even a co-op mode. So we are stuck with 10 or so songs, none of which are really great. Nobody wants to sit by themselves and play through all the "sets" just so we can play different songs. The new button layout isn't really that great either. I am disappointed, my family is disappointed. Now I'm not surprised that this game was on a clearance rack for $20... it is garbage. You took something that was great and ruined it. Getting returned tomorrow and put back on the clearance rack.
