It's hard to speculate why Guitar Hero: World Tour is such a huge cultural phenomenon since it costs so damn much. When the game is bundled with its complete repertoire of fake plastic instruments, it seems like only the overpaid athletes featured in the TV spots (see above) can afford to buy it. The fine folks at Amoeba Music are belting out a collective "That ain't right!," because they're now holding a massive sale for Guitar Hero: World Tour on all gaming platforms. Aside from discounting the guitar bundle and stand-alone game, both the S.F. and Berkeley locations are taking $30 off the complete band bundle. The sale runs while supplies last, so hurry.
