Kansas City writes: "If there's a hotter video-game genre than rock-and-roll, I didn't get the memo. By now, almost everyone has heard of "Guitar Hero." This best-selling series lets players rock out using a guitar-shaped controller to strum along with alternative and classic rock hits. In 2007, MTV Games came along and one-upped "Guitar Hero" with "Rock Band." The game outfitted virtual garage bands with a four-piece ensemble, including bass and rhythm guitars, drums and vocals."
