Should this really be in the Donkey Kong series? I see it akin to how Mario Party/Kart is being handled. - AlphaTwo
Well, the Mario Kart category is part of the Mario series category. It just seems fitting, but if you think they should be seperate instead of sub-categories, feel free.
It just seems strange to lump it into the same game series consider there are no connections besides the characters showing up in the game.
That, to me, defines a series. Games with the same characters/theme/title. The categorization was really just for the sake of making things look neater.
