Mario Kart 8 Deluxe has been one of the most consistently popular games throughout the Nintendo Switch's lifecycle alongside Breath of the Wild and Super Smash Bros. Ultimate. Nintendo's high-speed kart racer got a big boost last year in the form of the Mario Kart 8 Deluxe Booster Course Pass, gradually offering players more racetracks from across the franchise's history. In the most recent wave of DLC, players also got its first new DLC racer in the form of Birdo, with the suggestion of more characters to come.
