Mario Kart 8 Deluxe has proven to be a huge selling point for the Nintendo Switch since its release back in early 2017. Despite originally being a Wii U game, it found new life on the Switch's much larger install base of players, and has gone on to be one of the platform's most popular multiplayer offerings. To date, it has sold over 53 million units, ranking it at the top spot among the best-selling Nintendo Switch games of all time.
