While helpful to understand the notion of best response in simultaneous-move games, many economic settings allow for continuous, rather than discrete, action spaces, such as firms choosing how much output to produce, which price to set for their products, or how much to invest in advertising.

Repeated Games,ral rounds, which are known as “repeated games.” In real life, agents often interact for long periods of time, facing the same institutional or industry characteristics in each period (i.e., the same “rules of the game”).
