There’s a joke that capitalist eduganda game Monopoly needs to be updated to reflect the current economic situation. Nothing could be further from the truth. In fact, there is a rule that if all players are highly leveraged and one of them can’t pay rent, that player’s toxic assets will cause a collapse of the game:

You are declared bankrupt if you owe more than you can pay either to another player or to the Bank…If you have mortgaged MONOPOLY property you also turn this property over to your creditor but the new owner must at once pay the Bank the amount of interest on the loan, which is 10% of the value of the property.

This rule would cause Monopoly to be non-zero sum except that the rules also state “the last player left in the game wins the MONOPOLY game.” This imitates life because the last bank to go bankrupt is the mostly likely to get bailed-out.
