Reminds me of the story on how "Settlers of Catan" was created.

"Every once in a while, he would bring the new game upstairs to test it out on his family. They would play along, but Teuber could tell that the game wasn't working. Sometimes, in the middle of a match, he would notice his youngest son, Benny, reading a comic under the table. Other times his wife would suddenly remember a load of laundry that needed immediate attention. After each of these sessions, Teuber would haul the game back downstairs for further refinement. He repeated this process over the course of four years..."
