Abstract
One of the most important elements in games is 'fun'. According to the Flow theory, when the proper ability and challenge are combined at the optimum shape, game users can reach the stage of 'fun' with being fully absorbed. MMORPG satisfy the users making them have fun, using tools such as vicarious satisfaction by various role performances of various occupational clusters, self-display and diversity of the story through many quests. This study investigates the composition and characteristics of MMORPG, provide a model which calculates game balance according to the occupations and roles of the game characters and verify the validity by applying this model into the actual game. MMORPG is basically based on human behaviors. That is to say, it is possible to make balance evaluation model because the abilities needed for battle and adventure are within our imagination. For example, in the battle, 'power' is needed basically, 'speed' is also needed for quick movement and skillful technique, 'intelligence' and 'wisdom' are needed for more difficult techniques, 'strength' is needed to live on and 'charisma' is needed to make relationships. Thus, general six abilities are available, and based on these, by itemizing the contents composing the battle, the study attempted to provide the final battle balance evaluation model. Therefore, in order to make balance among these offenses and defenses and to compare the figures by unified ones, ICF (Integrated Comparative Figures) is hereby defined.
