This study is for a linkage between background story and ideal story. In MMORPG, it is very hard to follow main plot, which is called a background story, because story of MMORPG is determined by each player’s performance, which is called an ideal story. The detachment of these two stories lowers sense of presence in game world. MMORPG players who do not know about background story tend to pass over reading quests, and just stick to get to higher level.
The main purpose of this article is connecting these two stories by designing addon program. This addon program is based on analyzing meaningful game logs. During the game play, the addon program collects logs which are related to the background story. And these logs are presented to each player. Therefore, she can figure out what she is doing for the world now.
