Wii U System Update 5.3.1
Mario Kart 8 has definitely passed the honeymoon test. It’s still a staple with my group of friends, and the sheer number of tracks will likely ensure that over time, it will be my most played Mario Kart ever — that’s not even including the 2015 DLC.
Recently though the game had some issues with the YouTube enabled Mario Kart TV function, which completely stopped a lot of users from uploading videos. Nintendo has addressed this in the Wii U’s new 5.3.1 system update, which fixes the problem and adds some stability upgrades to the console itself.
