Mario Kart 8 is now the top selling Wii U game of all time!

In reality though it already was for like half a year now.

Lol at the Polygon guy. In what world would Mario Kart 8 only sell 1.26m? I wouldn't be surprised if the tally is at around 10m for this game when the generation ends. At the very least it will beat Double Dash.
