Rock Band allows players to perform in virtual "bands" by providing up to four players with the ability to play three different peripherals modeled after music instruments (a guitar peripheral for lead guitar and bass guitar gameplay, a drum peripheral, and a microphone). These peripherals are used to simulate the playing of rock music by hitting scrolling notes on-screen. Players using the Xbox 360, PlayStation 3 and possibly Wii consoles can interact through both online and offline multiplayer capabilities. In addition to the songs shipping on the game disc, hundreds of new tracks will be made available as downloadable content. It is unknown if the Wii will distribute downloadable content for the game.[9] The game has received universal critical acclaim[10] and has sold over 1.5 million units over all platforms.[11]
