Mario Kart Live: Home Circuit supports up to 4 players

When Mario Kart Live: Home Circuit was first revealed, all the footage and assets made it seem like the most you could get in an multiplayer session was 2 players. Turns out that's not the case at all. As long as there are four people who have the whole setup (Mario Kart Live: Home Circuit software, kart, and a Switch), you can have four racers go head-to-head...to-head-to-head. You'll have to make some pretty wide courses to give everyone in the race a fair chance, but it's still possible!
