Putting Callois into a 2-axis graph
Callois describes his 4 categories of play in the shape below, although i don’t see it diagrammed as such. Categories on the diagonal axis are incompatible, categories on the same side of the vertical axis are related to each other in one rough fashion, and categories on the same side of the horizontal axis are related to each other in another rough fashion. I’m playing with labeling the axes.
