TropeTwist is a system that analyzes and generates narrative structures in video games using interconnected “tropes” to create abstract and generic narrative graphs. Games are considered complex and multi-faceted systems with common elements grounded in underlying narratives. Identifying and describing these elements is a challenge as players might encounter narratives differently, and generating them requires encoding, interpreting, and evaluating them. The system allows for the creation of narrative structures using different tropes and examples of three games are provided to demonstrate how the system works. The system also uses MAP-Elites to evaluate and evolve coherence and interestingness in both hand-made and generated narrative graphs.
