Consider the following entry game. Here, firm B is an existing firm in the market, and firm A is a potential entrant. Firm A must decide whether to enter the market (play "enter") or stay out of the market (play "not enter"). If firm A decides to enter the market, firm B must decide whether to engage in a price war (play "hard"), or not (play "soft"). By playing "hard", firm B ensures that firm A makes a loss of $1 million, but firm B only makes $1 million in profits.
