There is a growing interest in producing story based game experiences that do not follow fixed scripts pre-defined by the author, but change the experience based on actions performed by the player during his interac-tion. In order to achieve this objective, previous ap-proaches have employed a drama management compo-nent that produces a narratively pleasing arc based on an author specified aesthetic value of a story, ignoring a player’s personal preference for that story path. Fur-thermore, previous approaches have used a simulated player model to assess their approach, ignoring real hu-man players interacting with the story based game. This paper presents an approach that uses a case based player preference modeling component that predicts an interestingness value for a particular plot point within the story. These interestingness values are based on real human players ’ interactions with the story. We also present a drama manager that uses a search process (based on the expectimax algorithm) and combines the author specified aesthetic values with the player model.
