Consider the game with the payoff matrix below, in which Firm $1$ and Firm seek to choose between Format A and Format B$.$

$\backslash$table$[[,$Firm $2$: Format A$,$Firm $2$: Format B$],[\backslash$table$[[$Firm $1$:$],[$Format A$]],$$$6,$$$6,$$$2$ $$8],[\backslash$table$[[$Firm $1$:$],[$Format B$]],$$$8,$$$4$ $$4]]$

If Firm $1$ chooses Format B and Firm $2$ chooses Format B$,$ their payoffs are

Firm $1$ gets $$8,$ Firm $2$ gets $$2.$

Firm $1$ gets $$2,$ Firm $2$ gets $$8.$

Firm $1$ gets $$4,$ Firm $2$ gets $$4.$

Firm $1$ gets $$6,$ Firm $2$ gets $$6.$
