Trivia

 * Much of the Mario Kart Wii (except Toad's Factory, Mario Circuit, and Daisy Circuit) and Mario Kart 7 tracks would go on to appear in Mario Kart Tour, as well as the Mario Kart 8 Deluxe - Booster Course Pass.
 * However, it's still possible for Toad's Factory, Mario Circuit, and Daisy Circuit to reappear in both Mario Kart Tour, as well as the Mario Kart 8 Deluxe - Booster Course Pass.
