Thus, if you see "Mario Kart 8 Europe ENFRDEESITNLPTRU REV 4" on a listing, you are looking at a disc that was likely produced in the final months of the Wii U’s lifecycle (circa late 2015 to early 2016), destined for retail shelves in Russia, Portugal, and Scandinavia. It is, functionally, the "Complete Edition" of Mario Kart 8 on Wii U, even if Nintendo never officially called it that.
