Abstract: A practice mode can be inserted into an RPG program without giving the player a sense of boredom. Because the distinction between the practice mode and the game is eliminated, the player is not given the sense that the progress of the game is being interrupted and the problem of the player losing interest can be resolved. Also, because of the construction of a new training system wherein training for special moves, that are difficult to remember, is easily stored on the screen, the player can focus on the progress of the game and can have increased interest in the game.
