Spacetime games subsume causal contextuality scenarios

We show that causal contextuality scenarios are equivalent to a subset of the formerly published spacetime games, which generalize game theory to decisions arbitrarily located in Minkowski spacetime. This insight leads to certain constructs and proofs being shorter, simpler, and more intuitive when expressed in the spacetime game framework than in the causal contextuality scenario framework. This shows that the insights of both frameworks taken together can contribute positively to advancing the field of quantum foundations.
