Big thanks to Scott for pointing this out to me.
In the past I’ve focused on those activities that span games, puzzles, plot and mystery (I’m guessing ARGs and adventure games would fit in here) as those, for me, were the ones most closely linked to learning. However, I’m now wondering about the potential of magic for learning and how game theory might fit in. This taxonomy has opened my eyes to other possibilities.
Also, I now realise that my knowledge of offensive-sounding card games is sadly lacking.
