If work was more like games and play

What would work look like if it was more like a game, and playing the game was more like playing in the sand with you pals at age four? My guess it that it would be more fun,  effective and stimulating than today. This is my reasoning:

• When we play a game, we readily, without objection, accept the rules of the game. No matter how ludicrous they might we, we simply accept that if we want to participate in this game we must obey to some laws that someone set up. And no matter how we roll the dice or upgrade our level 56 Blood Orch Mage we still accept these constraints.
• On the other hand, when we used to play in the sandbox at kindergarten, we would dream up the most amazing stories of dragons, beasts, cars etc. And the possibilities where endless. If we wanted the car to fly it could, no questions asked.

What if we could combine these two views, and take them with us into work. How easy would in not be to try out a new process or method? We just set up Scrum for example, agree on the rules and then play! And how magnificent would not our stories, solutions and conversations be if we would just allow us to dream as we once did?! I think we would be the most creative company in the world, and having a laugh doing it!
