Recently, analysis of bargaining game using evolutionary computation is essential issues in field of game theory. In this paper, we observe a bargaining game using co-evolution between two heterogenous artificial agents. In oder to model two artificial agents, we use a particle swarm optimization and a differential evolution. We investigate algorithm parameters for the best performance and observe that which strategy is better in the bargaining game under the co-evolution between two heterogenous artificial agents. Experimental simulation results show that particle swarm optimization outperforms differential evolution in the bargaining game.

Educational games offer an opportunity to engage and inspire students to take an interest in every subject material in school. The "fun" obtain when playing games become a trigger for the use of games in learning. However, there are doubts whether the players actually learn while they are having fun. Vidyanusa is an Online Mathematics Education Game being developed by Crayonpedia Education Ecosystem in Indonesia. The learning goal of Vidyanusa is to engage junior high school students in learning mathematics. In this paper, we design the Vidyanusa game material Functions and Relations by using Balanced Design Approach. This approach has three models in succession; the Content Model outlines the purpose of the game, the Task Model maps out the mission, and the Evidence Model outlines student measurement. This paper will then discusses the quality of games produced in term of Usability factor for effective results and objective. The measurement of the game was carried out based on International Standard ISO/IEC 9126-1 FDIS about Software Quality Product.

The process of game development is contained of many steps that is hard to forecast success or failure. In order to develop successful game, the development period should be shorter, which could reduce development cost. In order to reduce development period and cost, it is needed to make a communication among planners, programmers, graphic designers and investors lively with a prototype as a communication tool. In this study, the concrete examples are demonstrated how to use prototypes as a tool for communication and feedback of team members, in the process of game development. This paper explains the characteristics of various types of prototypes according to types of game contents. This paper demonstrated two types of prototype according to development stage, one type is a prototype to gather feedback in the planning stage, the other is a prototype to make team members cooperate and communicate in the stage of production stage.

To strengthen the competitiveness of the game industry, one needs to develope a tool for evaluation of the satisfaction level of the game users, which leads to the improvement of the quality of games and increment of the amount of game trade. In this study, we developed factors to measure the satisfaction level and estimate their distributional properties. For the purpose, using a survey data for RPG games, we discussed several aspects for normalization of score distribution for satisfaction factors and estimated their density function by use of parametric density estimation of SAS/INSIGHT. We believe that the proposed results help us to predict or estimate the satisfaction level of newly developed games as well as the current popular games.

As commercial game engines become available to the public, attempts have been made to use it for general purpose research. This study uses the game engine to develop a medical simulation. Specifically, when the user selects an important portion of the human body, the focus+context visualization is applied to the volume data. We proposes the accumulation based method to make the background part more transparent and naturally fuse it with the focus part. Since the proposed method combines well with the existing volume visualization, the virtual surgery function such as incision is performed smoothly. The game engine is useful for general-purpose research, because auxiliary functions such as collision handling and UI can be efficiently created with the help of it.

The computer game has a narrative structure, which scenario is proceeded by player's consecutive interactive. The interaction is the core of game plays that is not only storytelling in itself, but also is implemented by interface. The UI of computer game is as a tool for communication between player and game, which has been designed by usability on use. However, is it the necessary for us to get synchronization of feelings about game scenario in terms of a psychological in order to deepen the pleasure that is the game's ultimate goal. Effectively, as a way to lead in this empathy. This study tries to application of storytelling to the UI that occurred player's interactive for the first time. Moreover, presented the result as the UI designs of casual MMORPG.

With the development of the Internet environment, various types of online reviews are being generated and exchanged among consumers to share their opinions. In line with this trend, companies are making efforts to analyze online reviews and use the results in various business activities such as marketing, sales, and product development. However, research on online review in industry related to 'Video Game' which is representative experience goods has not been performed enough. Therefore, this study analyzed STEAM community review data using machine learning techniques. We analyzed the factors affecting the opinion of other users' game review. We also propose managerial implications to incease user loyalty and usability.

This study was conducted with preliminary to develop the game contents for designing of sexual violence prevention serious game for school teachers. It is proposed to use of sexual violence prevention serious game with the analysis of the audience and a new approach. For this purpose, Gordon method and Service Blueprint method were applied in design thinking. The results from analyzing the audiences were to reflect the components of corresponding with the goal of the serious game, and interest and motivation for continuing education. Also, it was proposed to give the certificate of education participation to teachers attended in the serious game in-service education.

In-game cheating by the use of unauthorized software programs has always been a big problem that they can damage in First Person Shooting games, although companies operate a variety of client security solutions in order to prevent games from the cheating attempts. This paper proposes a method for detecting cheaters in FPS games by using game log analysis in a server-side. To accomplish this, we did a comparative analysis of characteristics between cheaters and general users focused on commonly loaded logs in the game. We proposed a cheating detection model by using artificial neural network algorithm. In addition, we did the performance evaluation of the proposed model by using the real dataset used in business.

The visibility of the aiming point used in shooting game based on the present interactive gun ride is too low. This research tries to improve the visibility to apply the aiming point used in FPS(Fisrt Person Shooting) game to interactive gun shooting game in order to overcome the problem of an existing bodily sensation type arcade game. This research try to investigate the effective visibility through the experiment that 20's college students took part in. We identify the optimal aiming point from the results of this experiment. We will determine the compatability to use in the real commercial game to apply it to the ride based shooting game.
