The Mario Kart franchise maintains a diverse and fun lineup of tracks by continually adding new ones based the latest Mario (and general Nintendo) games. Critically acclaimed Switch hit Super Mario Odyssey has no shortage of wonderful worlds to choose from, but it came out after Mario Kart 8 Deluxe, so it hasn't yet been represented. That's where the fans come in.
In the absence of official playable Odyssey tracks, Mario Kart Wii modders decided to step up to the plate and create one of their own. By re-working Mushroom Gorge, modder Luke Chandler was able to recreate Odyssey's Luncheon Kingdom as a new course. Although still a work in progress, Luncheon Kingdom is fully playable in Dolphin, and you can download it by clicking on the YouTube video above.
