Nintendo’s latest blockbuster release for the Switch console has become the company’s biggest debut on any platform, scoring 10 million sales globally in its first three days.

Pokemon Scarlet and Violet were released simultaneously on Nov. 18 and sold over 4 million units at home in Japan, also setting a new domestic record. The games are identical except for the lineup of characters and collectibles in each version. Nintendo had only recently reached its last domestic sales high with the well-received Splatoon 3 in September, auguring a successful holiday season for the games- and console-maker.

Nintendo shares were up as much as 1.9% in Tokyo on Thursday morning after the announcement.

Now five years old, Nintendo’s Switch console relies on big game launches to maintain momentum for its software and hardware sales. Animal Crossing: New Horizons was its runaway hit during the pandemic, when demand for home entertainment and gaming surged, but the latest Splatoon and Pokemon franchise entries have opened to even bigger sales.

Console rival Sony Group, for comparison, recorded its best first-party game launch ever this month with God of War Ragnarok, which sold 5.1 million units over its first week.

Both Japanese entertainment giants have offered cautious forecasts for the year ahead, as demand wavered over the course of this year. Nintendo sliced 10% off its fiscal-year Switch console sales forecast this month, citing prolonged shortages in chip supply as part of the cause. Company executives have said they remain confident in the Switch’s appeal despite its age.
