In this research, we developed two kinds of games, “game including Boredom Avoidance Elements(BAE)” and “not included game” from BAE survey of Role Playing Game. We divided test player into two groups with different playing conditions and compared the results of the questionnaire of two kinds of games. Asa result, it became clear how each BAE is effective against the motivation reduction. Moreover, we found that there is a difference in feeling depending on the playing conditions.
