Another feature I am throwing together with staff writer Tracy Erickson which should run tomorrow. We used a few sources for the data (NPD, VGChartz, and so on). Some games sold shockingly low. Our list is also just console stuff as tracking the nebulous world of PC games is damn near impossible regardless of what NPD says.
But we live in a world where Nintendogs sells 21 million units and Monster Lab sells 65,000.
