The SNES version of course
I’m still enjoying Mario Kart Live here and there.
As I noted in my impressions piece; the amount of fun you’ll get out of it really depends on how much space and time you have for it. You’re probably going to need a lot of space for this project.
As a “celebration of the 35th anniversary of Mario,” 3D-printing manufacture BCN3D managed to craft the entire Rainbow Road track from the original SNES Mario Kart. According to them, it took “two engineers and 10 employees” to make this “ambitious” build, which actually accommodates the Mario Kart Live car.
BCN3D says that the track is comprised of “more than 4400 3D-printed pieces,” clocking in at 5×5 meters. They’ve made all of the STL files available here at this Thingiverse landing page.
It is ambitious! I love that the track length is wide enough to fully fit the toy racer, while preserving the “hazard” of falling off. The sky really is the limit with this game, as you could theoretically raise the platform and put a soft surface underneath: penalizing drops and forcing the real-life racers to put the car back on the track.
