While most of the attention Nintendo gets these days involves the Switch (and that system’s recently revealed DIY cardboard toy controllers), the Nintendo 3DS platform is still killing it. Nintendo announced today that the 3DS family of systems just had its best month of sales since December 2014.

According to Nintendo, citing NPD Group sales estimates, the company sold more than 750,000 2DS and 3DS systems in the United States during the month of December. That’s a 27 percent increase over the same period in 2016, pushing 3DS hardware sales past 21 million in the U.S., Nintendo said.
