Students create board games based on materials they have read.
This works best for mythology or adventure text, but could work well with other types of literature as well. I have used this for years with Beowulf. Students are directed to use as many elements from the story as possible. Bragging, kennings, the exchange of treasures, long journeys, and so on are used by most game creators. I ask them not to merely copy a famous game they have seen or played, but to be creative.
