The May 2016 NPD report has just been issued, but not a single Nintendo title was featured in the top 10, first-party or otherwise. Nintendo hasn't remained tight-lipped however, and has issued a statement pointing out that its 3DS handheld has passed the 60 million units sold mark:

May was a milestone month for the Nintendo 3DS family of systems. Having recently passed 60 million units worldwide, the current generation's top-selling dedicated gaming platform welcomed an entirely new audience with a lower suggested price of $79.99 for the Nintendo 2DS system. This big value has already shown big results. According to the NPD Group, which tracks U.S. video game sales, in May the system saw a 38 percent sales boost over April and a 148 percent increase year-on-year – all after just one week at the new price.

Nintendo was keen to point out other commercial successes, such as The Legend of Zelda: Ocarina of Time 3D, a recent addition to the Nintendo Selects:

New owners of the Nintendo 2DS system are finding an instant library of incredible games, such as The Legend of Zelda: Ocarina of Time 3D, which reentered the NPD Group's top 25 best-sellers list nearly five years after its release. That game and other hit titles are available for $19.99 as part of the Nintendo Selects collection. Players can also look forward to plenty of exciting new games for the Nintendo 3DS family of systems this year and beyond, such as Pokemon Sun and Pokemon Moon this November.

Elsewhere, Nintendo highlighted the continued performance of Minecraft on the Wii U eShop:

On the Wii U console, downloads of Minecraft: Wii U Edition from Nintendo eShop grew more than 40 percent month-on-month thanks to the release of the Super Mario Mash-Up Pack, which adds fun Super Mario-themed content at no extra charge. The physical version of Minecraft: Wii U Edition, which includes the Super Mario Mash-Up Pack on the disc, will release on June 17 at a suggested retail price of just $29.99.

So while the lack of Nintendo games in May's NPD figures might be something of a blow, there are still some positives to take away. The 3DS might not be matching the DS in terms of sales, but 60 million units sold is nothing to be sniffed at - especially when you consider how poorly its rival the PS Vita has performed.
