Book excerpt: A comprehensive book explaining “applied RPGs”—using role-playing games therapeutically. Across the globe, therapists are using tabletop roleplaying games (RPG) such as Dungeons & Dragons as a part of their practice. This book provides an overview of what RPGs are and what makes them such an effective and powerful tool for therapy. By examining research on gaming, flow, immersion, and role-play, readers will gain a better understanding of the theoretical underpinnings and how to skillfully and ethically use RPGs in their own practices. The author also looks at the history of RPGs, specifically focusing on issues of diversity and representation to help providers understand some possible pitfalls that exist within the medium. The book utilizes an example group to walk through everything from conception, planning, running, documentation, and termination of the group.
