With the exception of the game box and rule sheet (which require regional translations), identical components are used in each version of the game.

Category of small categories Category of small categories In mathematics, specifically in category theory, the category of small categories, denoted by Cat, is the category whose objects are all small categories and whose morphisms are functors between categories. Cat may actually be regarded as a 2-category with natural transformations serving as 2-morphisms. The initial object of Cat is the "empty category" 0, which is the category of no objects and no morphisms. The terminal object is the "terminal category" or "trivial category" 1 with a single object and morphism. The category Cat is itself a large category, and therefore not an object of itself.
