As a student at DigiPen Institute of Technology, I led a game team of twenty talented game development students to make Barton, an experimental game that makes use of an open dialogue system. The game uses a large language model to allow the player to say anything they want to their NPC companion, while staying within the bounds of the human-written narrative. We also explore how an open dialogue system changes how players understand and bond with fictional characters, in ways never before possible.
