In “Wargaming for International Relations Research,” Erik Lin-Greenberg, Reid Pauly, and Jacquelyn Schneider present wargames as a method for international relations research. The article defines and differentiates wargames from other methods, provides guidance for using wargames for research, and concludes with an agenda for future study. The article is a generative work that provides a firm foundation upon which researchers can build methodologically and substantively. It raises far more questions than it answers, but that is not a limitation of the article. It is the hallmark of a major contribution.
