Another big month for Pokémon and a run on 3DS systems were the big Nintendo stories of the December sales in the United States.

In the combined-format top 10, Pokémon Sun and Moon (tracked separately) were #8 and #10 in the December charts. Combined, the two games have performed better than any Pokémon game since Diamond and Pearl in 2007 (a combined 4.21m to Diamond/Pearl's 4.25m, plus eShop sales not tracked by NPD). The 3DS was up 2% over December 2016, translating to about 560,000 units sold despite wide reports of shortages for the handheld during the month.
