Mario Kart Tour is total rubbish, which is par for the course when it comes to Nintendo's boring mobile games.
Loot boxes, frustration, bad controls, Mario Kart Tour has it all. More crucially, its glorified Battle Pass nonsense, the Gold Pass, looks absolutely abysmal next to the recent launch of Apple Arcade and Google Play Pass.
Nintendo doesn't really care about the mobile platform, but it's using the market to make tons of cash anyway.
