People have been experiencing lot of incidents for their lives which results in gaining their impetus. Each impetus derives an emotion and such emotion is either of positive or negative one. The positive emotion motivates activation of his life but the negative emotion demotivates one. Specifically, the negative motivation will be much worse for children and it could be adversely affected to their emotional development. The paper first characterizes how to regulate an emotion in a view of psychology base and also characterizes how to regulate the emotion for children. And then, we analyze serious game contents which have been developed to care a negative emotion for children and youth to derive some game elements to be used in the games. Finally, by combining the two characterizations of regulation of emotion in psychology view and the serious games, we propose effective game elements for caring children’s negative emotion. We expect that the results will provide a good guideline when we make a serious game to care children’s negative emotion.

The MORPG(Multiplayer Online Role Playing Game) is one of the popular online game genre that its game play is more addictive and it has longer playing time compared with casual-style online game. This property makes it possible for game company to derive stable revenue for a long time other than casual- style online game. So far, developing MORPG has been popular on PC platform and now it has been started on a smart phone platform due to advances of hardware technologies and MORPG gives a new game experience to smartphone users. In order to make a new MORPG on smart phone platform, we have to design various use scenarios that are characterizing users’ behavioral actions in the game. It is time-consuming but we could save the design time if we reference to those of MORPG on PC platform. The paper proposes systematic user play scenarios for MORPGs on PC platform by characterizing 「Dungeon & Fighter」 and 「League of Legends」 which are the most popular MORPGs on PC, these days. We present the whole user scenarios with flowcharts showing the characteristics of all possible users’ actions in the MORPGs. When we make a new MORPG based on a smart phone platform, our results will provide with an effective design guideline for its game design.

Today, social game is being one of the biggest growths on mobile and PC platform. This paper propose systematic user play scenarios for social games by characterizing 「FarmVille2」and 「AniPang」which are the most popular social games on PC and mobile, these days. We present the whole user scenarios with flowcharts showing the characteristics of all possible users’ actions in social game. When a game developer makes the game logic for a new social game, our results will provide with a design guideline for the game.
