The second edition of this book has the benefit of significant improvements on the first edition. The first was criticized for being incorrect at times; the second book is revised and improved. Generally, the book gives a detailed examination of game theory including all the essential elements. Its applications to the moral, political, and philosophic ideas are well developed and extremely interesting. "The book takes several detours to offer useful expositions of terms and debates such as methodological individualism, common knowledge, equilibrium, learning, morality, norms, etc." as the last review said. These detours prove worthwhile.
The book is difficult to follow and poorly organized, in my opinion. It takes significant work to find the essential ideas and suffers from a lack of "introduction". For those unfamiliar with game theory there are many introductory texts that give a better presentation of the basic ideas without having to work as hard. One of these I find particularly helpful is available online (I had found it for free): Game Theory by Turocy and von Stengel which was used as the introductory survey for the Encyclopedia of Information and Systems. Lawyers may find a short pamphlet produced by Kaplow and Shavell "Decision analysis, Game theory, and Information" quite a useful and practical introduction. The advantage of these texts is their length; both can be read within an couple of hours. Also, both of these provide a bibliography for further reading. For the mathematically inclined, the comprehensive treatment by Fudenberg and Tirole, Game Theory, is a classic for a reason.
This book is a worthwhile text and can spark significant thought and suggest great research; however, I fear it could scare too many off as an introduction to the (amazing) world of games.
