Explore the conceptual origins of wargames and role-playing games in this unprecedented history of simulating the real and the impossible. From a vast survey of primary sources ranging from eighteenth-century strategists to modern hobbyists, Playing at the World distills the story of how gamers first decided fictional battles with boards and dice, and how they moved from simulating wars to simulating people. The invention of role-playing games serves as a touchstone for exploring the ways that the literary concept of character, the lure of fantastic adventure and the principles of gaming combined into the signature cultural innovation of the late twentieth century.
My second recommendation is CG Lewin's "War Games and their History". It is a bit lighter on the history of military professional games, even if there is a chapter or two on that, but the chapters on non-professional wargames are amazing. The author has a personal collection of games going back to the 19th century and the book is full of photos and descriptions of obscure games that I really enjoyed reading about and that I never found in any other source. It covers games up to around 1950, so it does not get into any of the more well-known modern history of wargames (starting with Avalon Hill in the 1950's).

In some ways it reminds me of Jon Peterson's "Playing at the World", which thoroughly documents the origins and early history of D&D, which started the genre.
