Nintendo is racing into the holiday season with several major titles this year, and “Super Mario Odyssey” is leading the charge. Since the game’s release five days ago, the new Super Mario Odyssey video game for the Nintendo Switch system sold more than 1.1 million units in the U.S. alone. According to Nintendo, those stats make it the fastest-selling Super Mario game ever in the U.S., surpassing the New Super Mario Bros. Wii game. Super Mario Odyssey is also the fastest-selling game so far for Nintendo Switch.

The game has already been enjoyed by well over a million people, and is likely to be enjoyed by many more, as those early players continue to spread their excitement for Mario. On, which aggregates scores from certain reviewers, for example, the game currently has a critical review average of 97, with 43 perfect scores. This makes Super Mario Odyssey ($59 on Amazon) the best-reviewed game on Metacritic for any system of the last three years, tied only with Nintendo Switch launch game The Legend of Zelda: Breath of the Wild.

“The public continues to respond positively to Mario’s latest adventure,” said Reggie Fils-Aime, Nintendo of America’s President and COO. “We’re also seeing sales momentum for Nintendo Switch thanks to an ever-growing catalog of games from large publishers and indie developers.”

Nintendo has stated that the company has increased supplies of Nintendo Switch to meet demand through the holidays, but it can still be hard to find online. The total number of Nintendo Switch systems sold in the United States through the end of October now stands at more than 2.6 million.

The news comes just one-day after Nintendo announced the company’s Black Friday Deals for this year, which includes several Nintendo 2DS and 3DS bundles, as well as new titles for the Nintendo Switch. You will have to act fast though, as the 2DS and 3DS bundles will most likely be just as popular as the Nintendo Switch this year.
