Mario Kart 8 Deluxe

Nintendo's 2017 Switch port of the 2014 Wii U racer became the best-selling racing game of all time at over 64 million copies, outpacing Gran Turismo 4 by 52 million units. Its anti-gravity tracks, 96 courses with the Booster Pass, and the blue shell that has ended friendships since 1996 make it the ultimate multiplayer racer.
