Tragedy of the commons is a common macroeconomic and/or environmental game. One example is how much grass a cow can eat in a community. There are limited units of grass and the cows want to eat. It is beneficial for you, as a cow, to eat as much as you can. But if too many cows eat too fast, the grass cannot replenish and everybody dies.
