If you want to take a break from ideating, you can use this game for a good time as well. Start by mixing the two decks together, and draw two cards. Show those cards to everyone in the game, and start telling a story based on those two cards in only 20 seconds
For example, “In a world where energy is constantly available, everyone lives in a mixed reality world.”
The next person will have to continue the story. The person who exceeds the time limit will be eliminated.
