Nintendo announced today that Mario Kart is the fastest-selling Mario Kart title in the company's history. Through retail and digital stores, Mario Kart 8 Deluxe sold more than 459,000 copies on launch day in the United States. That puts the game ahead of the previous record holder, Mario Kart Wii, which sold 433,900 copies on launch day in the same region. Nintendo is touting a 45 percent attach rate for the game in the US.
Mario Kart 8 Deluxe has likewise sold quite well in another region. It topped the charts in the UK, making it the first Nintendo boxed game to do so since 2011. (Breath of the Wild did not take the crown because it was beat out by Horizon Zero Dawn.) The previous record holder there was Pokemon White for Nintendo DS in 2011. It's also the first Mario game to top the charts since... oh, it's Mario Kart Wii again.
We won't know the Media Create numbers for Mario Kart 8 Deluxe's Japanese launch, but we can expect to probably repeat the Western performance there.
Nintendo is hoping to keep up the Switch momentum with an anchor game for each month, including Minecraft: Nintendo Switch Edition (May 11), ARMS (June 16) and Splatoon 2 (July 21). Of course, we'll hear more with E3 2017 around the corner, as Nintendo has a major Direct planned around the show.
