My interest is in the intersection between AI directors, player modeling, and procedural content generation. Using a combination of these tools, I believe that we can expand the space of tellable stories to create a story that is completely driven by the player’s actions in the game. There are two use cases for this work. The first is adding additional content to an open-world game by letting the player influence the world after the main story is completed, which would help address the problem of replayability. The second is to allow the player to create a completely personalized story from the beginning of the game, using the starting situation of the game as if it was the start of a simulation.
