Jamais Cascio reveals futurism's secret: dungeon-mastering Dungeons and Dragons helps you build futures scenarios. It makes all kinds of sense. The scenario-runner is both situations aggregates and creates a stack of materials, manages the social interactions of participants, deals with eventualities.
Via IM Steven Kaye points out to me that running a game is no guarantor of being a fine futurist. Quite true. Think of the experience as a dojo for futurists, a field for learning, rather than an automatic sign of achievement.
If it's confessions time, I admit that running Call of Cthulhu campaigns is my gaming inspiration. It has the underground nature of D+D, plus madness. And books.
