This document summarizes a workshop on revising Johan Huizinga's book "Homo Ludens" for modern game studies. It discusses two main points: 1) Professor Jos De Mul proposes that games inherently involve "ambiguities" or ironic dualities, like freedom within rules, that account for their unique nature. He believes appreciating games requires accepting two opposing experiences at once. 2) This challenges the field's search for consensus by showing games defy binary definitions. Embracing ambiguities, as Mul and Tavinor suggest, may provide a more productive path for a unified theory of game studies.
