Crossplay

Is Mario Kart 8 Deluxe: Booster Course Pass crossplay?

Mario Kart 8 Deluxe: Booster Course Pass is only released on one platform, so there is nothing to cross-play with.

A total of 48 more courses from throughout the Mario Kart series are racing to the Mario Kart 8 Deluxe game as paid DLC*. Take in the sights and speed through courses based on real-world locations like Tour London Loop and Tour New York Minute. This DLC also brings back half-pipes! Get some air, pull off a trick, and get a speed boost on Merry Mountain and Wii Maple Treeway.
