The game control device may include a storage unit, a first match-up executing unit, a character ability updating unit, and a second match-up executing unit. The storage unit stores an ability value of each player character. The first match-up executing unit executes a first match-up between two player characters in response to input of a communication terminal, and to determine a result of the first match-up based on the stored ability value of each player character. The character ability updating unit updates, based on the result of the first match-up, the ability values of the two player characters, and causes the storage unit to store the updated ability values. The second match-up executing unit executes a second match-up between player characters independently from the first match-up without input of the communication terminal, and determines a result of the second match-up based on the stored ability value of each player character.
