Before the first player reaches the spot, the second player must vacate the spot by pointing to a third player and receiving a nod. If he receives a shake he must immediately find someone else until he gets the nod. This heightens the risk factor of the game. Even if you're planning quiet activities for the day, a high energy warm-up may be useful to release unfocused energy letting everybody get down to business. Don't be afraid of initial chaos.
All introductory activities serve a purpose.
They're not always interchangeable. The trick is finding out exactly what each one does and how to best serve your particular purpose. You can stay with a game as long as it's working. Don't be afraid to play it over and over if people still enjoy it.
