If you thought selling 1.2 million software units in 4 days was impressive, then get ready for this – Mario Kart 8 has continued racing off store shelves and Nintendo have confirmed that over 2 million units of the game have been sold through to consumers.

Whether you pin that on a lack of third party software for Nintendo’s struggling home console, the astute move of offering a free game on registration to Club Nintendo, or just simply how great and well-loved the series is, an attach rate of around 1 in 3 for a single piece of software is quite simply staggering. Let’s hope this marks a turning point in the Wii U’s life!
