The Nintendo Switch exclusive Super Mario Maker 2 was the best-selling game in June, followed by Crash Team Racing: Nitro-Fueled, while the Nintendo Switch was the month’s best-selling console.
According to the NPD Group, reporting the top-selling games of the month and the year so far, noted Mario Maker 2’s launch month surpassed both the original Super Mario Maker as well as the 3DS version’s respective launch months. Meanwhile, the Nintendo Switch is not only June’s best-selling console but also all of 2019’s so far. And, according to NPD, the Switch is the only console in 2019 showing year-over-year growth (it did, of course, launch later than both the PS4 and Xbox One.)
