Andy Pressman reviewed Playing at the World by Jon Peterson
On pretending to be other people doing other things, for fun
4 stars
An unparalleled history of roleplaying, from war simulations through modern ttrpgs. Plenty of digressions into topics like measuring fictional distances, the origin(s) and meaning(s) of the term 'orc,' hobby zine production and distribution, etc — overstuffed, if anything, but a delight for those who would enjoy opening every drawer in a cabinet of wonders.
