But if I had to put it in the most simple terms- this book looks at the shift from war-games to roleplaying games, and whether that shift is decisive (albeit elusive) or doesn't exist (and illusive ... ahem). More importantly, it looks at the history of the communities that grew up around the early RPGs, and how these communities engaged in conversations about what RPGs were... and by conversations, I mean .... debates. Finally, we see that these debates continue to echo over and over again- I would say that looking at enworld, a good number of the conversations we are currently having about D&D and RPGs in general would not look out of place in Alarums & Excursions in the 1970s.
