As game budgets get fatter and the profile of the medium gets bigger, a whole new audience will exist with a demand for games that involve meaningful social play and interesting characters. While the techniques and concepts laid out in Dr. Isbister's book are useful for improving the fiction of games, in the form of writing, audio and character art, an experimental designer can infer some groundbreaking mechanics from this text. I'm personally working on an experimental indie game that hinges on inter-character drama, and Dr. Isbister's ideas have served as one of my primary sources of inspiration.
