The Wii doesn't really sell games either. The attach rate for the console is poor in comparison to its competition. Even though the Wii sold 30% more units worldwide than the Xbox 360, they only sold 13% more games worldwide. In North America, the biggest market for console games, the total number of Wii games sold is roughly equal to the total number of Xbox 360 games sold.
