Trevers is correct. The contracts preclude you from repurposing the content for a competing format. So, you could make a novel, a movie, a comic book, a TTRPG book/setting, a board game, a collectable card game, or an open-world computer game (like Witcher or Skyrim), but you can’t use the same content in a CYOA book, a Visual Novel, or another IF language like Twine, Ink, Ren’Py, Inform, etc etc.
