It's Mario Kart for those who do not have a Nintendo console for Mario Kart. In terms of mobile games, it's pretty fun and has a good cast of returning characters and newcomers. Personally, I hope they add E.Gadd and bring back R.O.B. However, the game was pretty greedy with its gatcha mechanics. With the gatcha largely removed, I would recommend starting the game if you haven't already. For those who do not want to spend any money on this game, I strongly suggest saving rubies only for characters, Mii costumes, or/and vehicles/vehicle parts that you want.
