The evening sky is getting dark and the first stars begin to appear. Everybody is getting cosy and warm but something is missing. Then somebody starts telling a story. This setup could have happened at any time and anywhere in human history - it might have included even our hominid ancestors. There is something inherently human in the scene. The story and the process of telling it - they cannot be separated from one another. Telling stories is how we construct our memories, how we pass on our values and communicate our experiences. It allows us to have a glimpse into another person's mind. Just us, and the story. This book tells a story, a story of how stories could be told using digital media. In many occasions digital media is said to revolutionize or disrupt the way things have been done before. This is not what we are claiming here. Digital storytelling is not about disruption, breaking or replacing old order. How could it? The stories will remain stories as before. Rather, this will bring stories back to where they once were. They will become alive, and include our digital world in them. Someone will tell the story - human or computer - to somebody else - human or computer. This will be the new digital campfire. Acknowledgments First and foremost the authors would like to thank Harri Hakonen for his early involvement and initial work in analysing the material and having sharp views and insights into the essential matters. We would like to thank the team at Wiley for their efforts, especially our editor Sandra Grayson and managing editor Juliet Booker. We are grateful for their flexibility during the trying times of the COVID-19 pandemic that have rattled up also our writing process. Jouni. I want to acknowledge the important role that my late friend and colleague Timo Kaukoranta played twenty years ago in launching this expedition into the world of interactive storytelling. I express my gratitude to the valuable input from the students over the years, and I am indebted to everybody who has attended my courses on interactive storytelling at the University of Turku in 2004-20. My special greetings go to Lilia and Julian: I am always amazed by your fantastical storyworlds, and, now that I am done writing (at least for a while), I will be happy to spend more time hanging out there with Lord Kanther, D'opa, Härpats and your other marvellous creations. And Iris, thank you for being there - living, laughing and loving. BGT. I wish to thank the hobbyist associations of Turun science fiction seura, Turun yliopiston tieteiskulttuurikabinetti and Turun yliopiston rooli- ja strategiapeliseura for providing for inspiration and insightful discussions relating to storytelling and games. I also wish to thank everyone I have played role playing games and live action role playing games with, especially those who endured the most ridiculous and embarrassing clumsy experiments of mine on this field of interactive storytelling. Loving thanks also to my dearest wife and role playing company, Riikka. Natasha. I wish to thank fellow authors of this book, it has been an amazing journey and inspiring collaboration which is one of many to come. I also want to thank IGDA Finland, Turku Game Hub and MiTale teams for all the support and tireless discussions on the topics of interactive storytelling and 'industry' views. I wish to dedicate special gratitude to my family, Petter and Sara, for endless support and inspiration. Petter. I want to thank Åbo Akademi University for keeping me on as a researcher after finishing my PhD during the writing of this book, my fellow authors for their patience and expertise, and of course to my family and friends for their support.
