I get you. It was essentially a dollar a track for the WiiU DLC tracks. This is around 50¢ a track but ask yourself:I'm probably wrong, there just seems to be a lot of misreporting going on at the moment. Btw, going by Wii U prices this DLC seems very cheap, which is unlike Nintendo.
Did Nintendo sell enough copies of Mario Kart 8 for WiiU to write off $1 tracks? Did Nintendo sell enough copies of Mario Kart 8 for Switch to write off 10¢ tracks?
