It very much does. Boosting, a one of the best off the shelf ensemble classifier is derived from a game theoretic formulation. Besides that there is this huge body of literature about prediction under non-probabilistic sequence of test cases. This line of work is primarily held up by game theoretic arguments and that of online convex optimization.
