[KineticLensman]

...Games contain tropes (story elements)

...Recognising tropes in a given game can be challenging

...Using them to generate game narratives can be challenging

...Tropetwist can generically describe the story structure of a game

...It can create a graph of a game's story and then variations of the story

...These variations can then be measured in terms of their coherence and interestingness, which in turn affect their playability

Or something like that
