This book fills a genuine need in the emerging field of game design for a collection of key texts on game analysis and criticism. Written and designed to accompany Katie Salen and Eric Zimmerman's earlier textbook Rules of Play: Game Design Fundamentals, The Game Design Reader can be used in the classroom or as a resource for game design practitioners. Thirty-two classic and cutting-edge essays by game designers, game journalists, game fans, sociologists, media theorists, and other writers from diverse fields consider foundational questions: What are games and how do they function? How do they interact with the culture at large? What critical approaches can game designers take to create meaningful experiences for players? Salen and Zimmerman have collected writings that span nearly 50 years of game analysis and offer a wide range of perspectives. Game journalists describe the rhythms of gameplay, game designers explicate their designs, sociologists consider such topics as role-playing in virtual worlds, and players offer their hands-on opinions and rants. Each text is "teachable": it can act as a springboard for discussion, a class assignment, or a design project. Each text offers insights to the professional game designers or scholar as well. The book is organized around a series of "Topics" -- ideas fundamental to the study of games, or emerging areas of research -- each of which is introduced with a short essay by Salen and Zimmerman that points to relevant texts in the Reader. "Interstitials" -- visual essays, documents, game ephemera -- act as counterpoint to the texts themselves.
