Jack Palance throws a gun at the feet of a shepherd and says "Pick up the gun" to goad the shepherd into action. The shepherd complains at first, then tries to pick it up and shoot. And he is killed by Jack.
"You all saw it", declares Palance, "He had a gun".
The throw down is a scenario.
The gun is an action.
The likely reaction of Palance is a factor.
There is pressure, a risk of death.
"Pick up the gun"
This is what games are.
