A game system and method for realizing artificial intelligence of a game character by user setting are disclosed. A finite state machine input module for receiving a set value by a user with respect to an operating state by artificial intelligence of a game character; A finite state machine editor module (FSM) for changing and setting an operation state of the game character according to the input set value; A finite state machine execution module is configured to execute the artificial intelligence operating state changed by the FSM editing module before or during the game, to the game character and execute the FSM execution module. According to the game system and method for realizing the artificial intelligence of the game character based on the user setting described above, even if the user enjoys the game, the setting of the artificial intelligent action of the game character is changed in real time, So that the non-specialist can change the real-time game environment and enjoy the game in various ways.
