When I wrote the comment, I explicitly thought of poker, chess, the Settlers of Catan and Wizard, all of these games where thinking with probabilities (w.r.t. the opponents' cards / the opponents' actions and the state of the board / the opponents' actions and the roll of the dice / the opponents' cards, respectively) can be more or less helpful. In the end, I chose diplomacy because additionally, it shares the characteristic of simultaneous moves.
