I dedicate this book to my long-suffering wife Kathy, who has supported me emotionally and financially for thirteen years as I have worked on interactive storytelling, patiently enduring my endless promises that “commercialization is just around the corner.”
My thanks go to Laura Mixon for serving as sounding board, mother confessor, critic, and fellow explorer as I have groped through the complexities of interactive storytelling. Thanks also to Dave Walker for his many contributions to the development of the Erasmatron technology, both technical and artistic.
Lisa Lord, Mark Barrett, and Aria Danika struggled through the morass of my verbosities and helped me clean up the mess, de-polysyllabic-ize my vocabulary, and actually make some sense. Linda Harrison, Stephanie Wall, Wendy Sharp, and Andrei Pasternak provided top cover, bottom cover, and side cover for the project. The gestation period for this book, about 21 months, was the same as an elephant’s, and now we all know what an elephant pregnancy feels like.
