We explore the role that story generation feedback may play within the creative process of interactive story authoring. While such feedback is often used as ‘debugging’ information, we explore here a ‘cocreation’ view, in which the outcome of the story generator influences authorial intent. We illustrate an iterative authoring approach in which each iteration consists of idea generation, implementation and simulation. We find that the tension between authorial intent and the partially uncontrollable story generation outcome may be relieved by taking such a co-creation approach.
