For the first time since its 2017 debut, the consistently well-selling Mario Kart 8 Deluxe is no longer one of the top 20 best selling games in the United States for a given month.
Honestly this is a pretty big deal. Mario Kart 8 has been an absolute sales juggernaut. It's been largely speculated that mario kart 9 has been delayed just because 8 keeps on making millions. It's just so uncommon to see a game sell in such huge numbers for over 6 years like that, especially because the game itself is way older than that and it didn't even get any expansions/dlc until very recently.
