Thats not the use of zero-sum used in economics or in (some applications of) game theory: any game with a discrete victor is a zero-sum probability of winning.

Thats not the use of zero-sum used in economics or in (some applications of) game theory: any game with a discrete victor is a zero-sum probability of winning. What is not zero-sum is the amount of money/points floating in monopoly. If you played a monopoly tournament where players can resign, and at the end of the game you sum up all the money as points for a final ranking you would see monopoly is truly non-zero-sum.
