I am but I can't because I don't have a USB and my computer doesn't support SDs.
I have Mario Kart 8 Deluxe, Mario Kart 8, Mario Kart 7, and Mario Kart Wii.
I have MK SC, MK Wii, MK7, and MK8 (Wii U).
were the 3 or so new characters really worth buying what is essentially the same game twice
I thought the fact that the battles actually had new courses was neat, along with the 5 different types of battles. In Mario Kart 8, it was just a Balloon Battle with courses you could play in regular mode.
That is true but don't you consider selling your Wii U version of MK8? I mean it is kind of just wasting your money to buy 2 versions where one has all of the characters, including the DLCs, and a better version of the Balloon Battle.
