Activision's certainly been pushing the bar with the "<Music type> Hero" games this year. Multiple, multiple Guitar Hero editions, Band Hero, and of course the "oddball" for this year is DJ Hero, which requires a completely new controller that looks vaguely, kinda-sorta like a single turntable.

Is it good? Reviewing this one is strange. Musically, either people are going to absolutely love it, or their mind will recoil from it. Mechanics-wise, the controller definitely leaves room for some questions. Can I recommend it? Well... definitely, if you're interested, try borrowing it from a friend or stopping at a store kiosk to give it a try first.
