DJ Hero could end up being the most divisive video game ever created. It flies proudly in the face of certain qualities I've come to expect of the casual-aimed rhythm genre -- qualities such as accessibility, recognizability and general ease of play. Activision's latest possesses none of these characteristics: It's got a sheer learning curve, it exclusively features music that has been mashed into an indistinguishable pulp, and it's easily the most difficult peripheral-based rhythm game I've ever played. (Dance Dance Revolution notwithstanding, of course. These legs just weren't made to flail.) Everyone who plays DJ Hero will either hate it to its core, eject the disc and toss in a more familiar musical standby, or, if they possess a certain collection of odd inclinations, they'll fall wildly in love with it. I fall into the latter group, though the small assembly of friends I recently had try their hands at the game fell firmly into the former. Yes, those people aren't writing this review, but I thought it important to note their existence. For my part, I found DJ Hero to be fresh by every conceivable definition of the word.
