Hom Ludens 2.0 is probably enough for me. Key points: Digimedia encourages playfulness because it's easy to take apart without breaking it.

If you analyse a film, it soon becomes broken. You need the willing suspension of disbelief. The same is not true of digimedia because of infinite deferral. This is a half-thought.

Young people play with sexual identity online. This confusion will cause problems for the oldsters. Who are used to geography not topology. You can be in two places at the same time.

Make-believe is mimicry. Learning was too much alea. New sim-learning can be agon and ilinx. This is a crucial crucial point. Allocentricity FTW.
