DZ: "Revolution does not come cheap. $200 million and 20 months work saw Harmonix and Electronic Arts release Rock Band, the game EA will hope does for downloadable content what the iPod did for MP3 players. Historically, music games such as Guitar Hero were limited to one instrument and a maximum of two players, whereas Rock Band allows up to three friends to play music across a range of instruments at the same time. Players around the world quickly donned their spandex, ran a comb through their power mullets and were ready, axes in hand, waiting to rock."
