NPD data for the month of March 2018 has been released. This month includes the release of Kirby Star Allies, so we are getting our first information on how the game did. According to The NPD Group, “Kirby Star Allies has had the strongest debut month of sales in the U.S. in the franchises’ history. The Switch side-scroller had a 90 percent better debut month than 2002’s Kirby Nightmare in Dreamland, which last held that distinction”. The success of the Nintendo Switch is credited for the game’s success, saying that it has been “giving Nintendo’s franchises a boost”.
