This study takes an analytical approach to the world of role-playing games, providing a theoretical framework for understanding their psychological and sociological functions. Sometimes dismissed as escapist and potentially dangerous, role-playing actually encourages creativity, self-awareness, group cohesion and "out-of-the-box" thinking. The book also offers a detailed participant-observer ethnography on role-playing games, featuring insightful interviews with 19 participants of table-top, live action and virtual games.
