Side Quest, A Visual History of Role Playing Games

This was both delightful and also a little all over the place. Which makes sense, there are a lot of different parts to RPGs (war games, role playing, D&D, fan groups, theater, figurine painting) but I was thinking it might be a bit more linear and in some cases had trouble keeping track. The author and illustrator each came to RPGs from different avenues (and are themselves in parts of the book) which made it more enjoyable.
