I just completed a game theory book (Game Theory Evolving, Princeton University Press, 2000). To find the best way to present various materials, I went through virtually every game theory book in existence. For the presentation of the basic material on normal and extensive form games, nothing even came close to this book in clarity of presentation and depth of understanding of the issues. Most textbooks, even highly touted ones that are mathematically challenging, do not even come close, and rarely even present the material in a coherent form at all.
I used to do a lot of carpentry, and I always knew the good carpenters from the run of the mill. The latter talk about how to build stuff. The good ones talked about how you choose, preserve, treat, and sharpen your tools. Myerson is, for game theory, like the good carpenter, and this book is more about the nature of the tools of game theory than their deployment--although it is certainly that, too.
The subtitle of this book is silly ("The Analysis of Conflict"). Game theory is the analysis of cooperation as much as conflict, and much, much else as well. So is this book.
