The Nintendo Switch is selling fast and breaking records at Nintendo. The company announced today that the new console has sold faster in its launch-month than any other video game system in Nintendo’s history. The Nintendo Switch system sold more than 906,000 units in March, according to the NPD Group, which tracks video game sales in the United States. That makes Nintendo Switch one of the fastest-selling video game systems of all time. Notably, this sales surge was accomplished in a nontraditional month for a console launch.

A lot of that success can be attributed to “The Legend of Zelda: Breath of the Wild” game, which the company claims to have sold over 1.3 million units. That total includes more than 925,000 units sold for Nintendo Switch and nearly 460,000 units sold for the Wii U console. That means that Nintendo sold more of this game for Nintendo Switch than it sold Nintendo Switch systems. That gives an attach rate of more than 100 percent. Nintendo explained that this could be attributed to people who purchased both a limited edition of the game to collect, and a second version to play.

This was all enough to make The Legend of Zelda: Breath of the Wild the fastest-selling Nintendo launch game of all time, as well as the fastest-selling game ever in The Legend of Zelda series.

“Nintendo always strives to offer consumers something fun, new and different,” said Reggie Fils-Aime, Nintendo of America’s President and COO. “With its various play modes and the innovative features of the Joy-Con controllers, Nintendo Switch provides unique experiences that people can take with them anywhere and share with anyone.”

Nintendo also points out that these sales figures could have been even bigger, since Switch shipments have not yet been able to keep up with such a high demand. In a statement the company added, “Nintendo is working to make sure everyone who wants a system is able to buy one, and more systems are continually being shipped.” Those sales are expected to rise, as the Mario Kart 8 Deluxe game will launch for Nintendo Switch on April 28. As we reported earlier, the game will launch with more content than any other Mario Kart game in series history, including 48 racing tracks, new Battle modes, new characters and other additions.
