Changing and Transforming a Story in the Framework of an Automatic Narrative Generation Game

Abstract

We propose the concept of a game system that includes an automatic story-generation function based on a table-top role playing game (TRPG). In this idea, stories are generated or transformed based on communication between a “game master (GM),” who controls the story generation, and “players (PLs),” who change and transform the content of a story proposed by a GM. This paper focuses on the mechanism for changing and transforming a story proposed by the GM. In particular, the proposed mechanism has various techniques ranging from macro-level techniques, which are related to the entire structure of a story, to micro-level techniques, which are related to the partial structures of a story. For instance, when the GM is a real human, these techniques in the PLs, who are computer agents, can produce changed and transformed stories that were not originally conceptualized by the GM.
