most sold 1) WII obviously ( lacks in games and proper online play and hardcore gamers.. most of the people who bought it are kids in elementary...)
2) XBOX 360 (if you dont agree your a blind cow) ( neck in neck with PS3 in terms of games, has a better online although it costs money)
least sold3) PS3. Has not sold more than xbox 360 or the wii, awesome console though. free online is a bonus.
