Effective and Economic game evaluation before game publishing is very important for game development company. In this paper, we designed and developed an effective web based game evaluation system according to three major game genre including MMORPG, FPS, and web game. The proposed evaluation model consists of five evaluation items such as game interest, competitiveness, technology, earning power, and market value and has common evaluation items and independent ones according to game genre. To reflect characteristics of each game genre, we divided evaluation items into common evaluation elements and individual ones according to game genre. We applied the proposed system to two real games of a game development company and showed the result.

Online game industry is also making much efforts in developing games that have emotional disposition which is rapidly growing by the increase of emotional demand by the user. In the online game development that induces immersion stimulating the emotion of the human has the evaluation stage it must surely pass, and in this stage, emotional evaluation system is known as the evaluation method that one can verify the function, usage and human emotion desire of the game before its launching. Nevertheless, at this situation the studying result is absent in the verification of efficiency and validity of the emotional evaluation system, this study is to work on the availability and validity of the emotional evaluation system as the evaluation tool of the game comparing with the Jakob Nielsen's evaluation system through common user group which are the subjects.

Today, Educational serious games are occupying a large portion of the serious game market but there is a lack of the quality evaluation systems for providing useful quality evaluation information about educational serious game to user or developer. Although the existing metadata management system for serious game is developed, the system had not provided a function to manage the quality evaluation information for educational serious game. Therefor the development of quality evaluation management system of educational serious game is a very important challenge. We proposed design of the system for managing a metadata and a quality evaluation for educational serious game. The advantage of our system is that the system provide a lot of reliable useful information for general users and developers, and support an easy and convenient tool to manage the metadata and quality information to managers.

As the online game which is possible of large-scale multiple access enjoys popularity, the number of development by many online game manufacturers came to increase exponentially. But, the reason why the qualitative expansion pace cannot follow the pace of the quantitative expansion on games is that most of them are paltry enterprises except the leading enterprises which are occupying few competitive advantages, so there is no well-established production procedure, and accurate test before the launch isn't accompanied. Therefore, it doesn't cope flexibly to the expectable results. Now, important function is not embodied through the game feature checking stage of the same feature or is under the situation being used in finding out the fatal error of the specific parts. To this, this study collects the emotional vocabulary in the games to suggest the evaluation system that can evaluate the emotion the user feels while playing the game with the usage of the evaluation system that is leaned toward the existing usage evaluation system, and through factor analysis, we classify them into interactivity, interface and information factors and suggest the emotion evaluation system while designing the evaluation questions according to it.

During the past 10 years, serious game industry has been growing steadily. But the system which could stably and reliably provide metadata information and quality information related to serious game remained unexploited. Existing systems only support the basic management functions of metadata search centered. Therefore, we have developed an integrated system to manage the quality information of serious game as well as to improve the inconvenient details of the existing systems. And we designed quality evaluation elements and quality information supply-methods, and linked up them to the system. Furthermore, we conducted user's satisfaction assessment survey on the use of the system. The advantage of the system is that the system provide a lot of useful information for general users and developers, and support a tool to manage all information related to serious game by easy and convenient method for managers.

This study tried to find the source of the success of on-line game sites and the way how the absorption and the satisfaction would have the relationship with the intention-to-use of on-line game sites. The primary purpose of this study is to establish the empirical model on the determinants of on-line game sites. The research model of this study will have insights which are trigger to the higher dimensions on the model and to the importance of the evaluation criterions of game sites. The suggestions of the study are as follows. First, the precedent factors of research model were tested for the commonality with explorative factor analysis and then tried the confirmative factor analysis. Thus, the determinants in this model will be used for further study without an evaluation. Second, the factors which have a most significant effect on the mediating factor like the absorption are a skill of user and an activity of community. Furthermore, the information quality of game sites was most significant in the satisfaction of user. Third, the most factors which included in the research model were significant to intention-to-use, however, the system quality did negatively significant.

A tangible sports game is an exercise game that uses sensors or cameras to track the user's body movements and to feel a sense of reality. Recently, VR indoor sports room systems installed to utilize tangible sports game for physical activity in schools. However, these systems primarily use screen-touch user interaction. In this research, we developed a V-Catch Vision system that uses AI image recognition technology to enable tracking of user movements in three-dimensional space rather than two-dimensional wall touch interaction. We also conducted a usability evaluation experiment to investigate the exercise effects of this system. We tried to evaluate quantitative exercise effects by measuring blood oxygen saturation level, the real-time ECG heart rate variability, and user body movement and angle change of Kinect skeleton. The experiment result showed that there was a statistically significant increase in heart rate and an increase in the amount of body movement when using the V-Catch Vision system. In the subjective evaluation, most subjects found the exercise using this system fun and satisfactory.

This paper present a design and implementation of a Contents Management System (CMS) to be integrated into a game that uses a Digital Game-based Learning (DGBL) approach for helping tourists learn about tourism spots as a part of the Package Tour Application. In terms of design, this paper shows a system architecture that consists of a database to store the game's content such as tourism spot information, score and question configuration, score history, et cetera, a web application to manage the content and a Rest API to delivers the content to the mobile game. Meanwhile, in terms of implementation, MySQL database and PHP programming language are used. Moreover, a time response performance evaluation is conducted which resulted in between 0.77 s to 1.4 s from CMS to the database. Once successfully integrated with the game, the CMS will allow the game to be played on multiple tours simultaneously, without having to rebuild the game for every package tour group.
