Pokemon Sun and Moon are the fastest Nintendo games in the company’s history to sell more than 4 million copies.
According to a statement from Nintendo, Pokemon Sun and Pokemon Moon came in number 2 and number 3 on the NPD Groups list of best-selling games for the month of December.
Combined, the two games have sold 4.5 million copies since their release in late November. The last quarter of the year was the “best-selling quarter for software in Nintendo 3DS history,” with 7.3 million copies of first-party Nintendo games sold during the three-month period.
Nintendo credited the Pokemon games, along with other new releases like Super Mario Maker for Nintendo 3DS and evergreen titles like Mario Kart 7, for giving the 3DS its seventh month in a row where sales grew over the same period the year earlier.
