The game script was more developed by applying complicated game scenarios and development of real-time game produce technique. However, systematical studies on game scenarios are relatively not enough Therefore, the purpose of the study is to reanalyze elements of game scenarios and to study on contents to be treated by game scenarios to apply the pertinent elements to the game script. To achieve the purpose, the study analyzed the existing researches treating development of game scenarios and researches on time-space expressive methods of game scenarios. On the basis of the results of the analysis, the study found necessary expressive methods to be applied jointly to game scenarios and examined their utility plans.
