The Nintendo Switch may not be the least expensive console on the market, but it sure is one of the most popular. Nintendo announced this morning that the Nintendo Switch is the fastest-selling video game system of this hardware generation over the last 21 months. The data refers to information from the NPD Group, which tracks video game sales in the United States.

From its launch in March 2017 through November 2018, the Nintendo Switch has sold more than 8.7 million units, outpacing U.S. sales of all other current-generation systems at the same point in their life cycles. The PS4 and Xbox One have been on the market much longer than the Nintendo Switch has, but a win is still a win.

Nintendo also became the top-selling U.S. software publisher so far for 2018, according to the same NPD data through November. This performance should receive an additional boost from the December release of the “Super Smash Bros. Ultimate” game, which has become not only the fastest-selling Nintendo Switch game of all time, but also the fastest-selling game in the Super Smash Bros. series, with U.S. sales of over 3 million units in just 11 days, according to Nintendo’s internal sales data.

“We are thrilled to see such a strong reaction from consumers in the second holiday season for Nintendo Switch,” said Doug Bowser, Nintendo of America’s Senior Vice President of Sales and Marketing. “We’re looking forward to delivering more excitement and smiles to our fans in the coming year and beyond.”

In the United States alone, Nintendo’s eShop sales have grown by 105% over 2017. “The Legend of Zelda: Breath of the Wild” and “Mario Kart 8 Deluxe” have sold over 4 million and 5 million units, respectively, and “Super Mario Odyssey” has sold over 4.7 million units.

In addition to the fast-selling “Super Smash Bros. Ultimate” game, other recently released games are also doing well. These include “Pokémon: Let’s Go, Pikachu!” and “Pokémon: Let’s Go, Eevee!,” which together total 2 million units, and “Super Mario Party” at 1.4 million.

The Nintendo Switch continues to be a best-seller on Amazon‘s charts as well. The portable powerhouse has an extensive lineup of games this year, even bringing in third-party titles like “Doom” and “Fortnite” from outside of Nintendo’s publication.
