Vibecoding an entire game with my son. It has NINJAS and MAGIC GREEN WOLVES and ZOMBIES, per the stakeholder's requirements. He's 4.
The product owner sets the vision: ninjas. Also magic green wolves. Also zombies. The requirements never conflict because he is four and his vision is total. I handle implementation.
Every build gets playtested the moment it compiles, with zero mercy and immediate, actionable feedback ("the wolf should be GREENER"). Backlog grooming happens at dinner.
