The document summarizes research on using game-based idea generation tools and techniques to help game developers come up with new game ideas. Several workshops were held where tools like card games were tested. The most popular tool allowed combining verb, noun and adjective cards. Overall the game-based tools were found to be inspiring and fun to use, generating many new game ideas. However, some tools were more complex and inefficient than others. Future work could involve refining tools and exploring their use at different stages of the game design process.
