From the introduction: This is the second of three essays on the three modes of role-playing collectively referred to as GNS, as presented in my essay GNS and related matters of roleplaying theory. The first of the three "support" essays was GNS 1: Simulationism: The Right to Dream. These essays' purposes are to clarify many aspects of their parent essay, to present the ideas that have always awaited a more general understanding of my basic points, and also to refine and develop the concepts based on the years of discussion and input from others[.]
