Online game business has emerged as the most lucrative entertainment industry, with over 10 million players in South Korea. The popularity of online games can be attributed to the availability of broadband network and the presence of numerous PC Bangs and around the country, which have pushed online games into the mainstream entertainment culture. The age distribution of online game players is expanding and a variety of new games are under development to target certain age groups. While the interactive entertainment market continues to expand, with many new online game publishers entering the market, relatively little is known about which factors influence online game players' behavioral intentions to play continuously in this area. It appears that in this extremely attractive and growing services segment, academics, as well as practitioners, would benefit from investigating the relationships among the players' loyalty, interactivity, the sense of presence and the impacts of several other key game-related constructs. Several types of interaction in on-line games and their relationship with the flow construct are investigated, and the resulting conceptual model is proposed. Based on data collected from online questionnaire survey, the validity of the simultaneous equation model has been tested and interesting conclusions have been developed concerning the relationships between the players' loyalty to the sense of presence flow, satisfaction and interactions. Other interesting results concerning game development strategy are also provided.

In online games, interactions with other players may threaten player satisfaction. Therefore, matching players of similar skill levels is important for players' experience. However, with the current evaluation method which is only based on the final result of the game, newbies and returning players are difficult to be matched properly. In this study, we propose a method to improve matchmaking quality. We build machine learning models to predict the MMR of players and derive the basis of the prediction. The error of the best model was 40.4% of the average MMR range, confirming that the proposed method can immediately place players in a league close to their current skill level. In addition, the basis of predictions may help players to accept the result.

In a dynamic game where the players move in a periodical sequence, each player observes the strategy of the others. So the players who move later in a game get to know the moves of others having made before them. Those who move earlier must take this into account in devising their optimal strategy. In the Poolco model, the bidding game is executed periodically. The player participating in the bidding game accumulates the information of its own and others'strategies, and payoffs through the repeated bidding process. Thereby, the players in this game would be able to map out how get the maximum profit, and get closer to the optimal strategy. This paper presents a mathematical modeling for a player to determine his or her optimal strategy at period T, based on the information acquired from the previous rounds for the periods, T-1, T-2, and so on. The proposed modeling is demonstrated with a dynamic fame theory.

Most of the conflict problems between 2 persons can be represented as a bi-matrix game, because player's utilities, in general, are non-zero sum and change according to the progress of game. In the bi-matrix game the equilibrium point set which satisfies the Pareto optimality can be a good bargaining or coordination solution. Under the condition of incomplete information about the risk attitudes of the players, the bargaining or coordination solution depends on additional elements, namely, the players' methods of making inferences when they reach a node in the extensive form of the game that is off the equilibrium path. So the investigation about the players' inference type and its effects on the solution is essential. In addition to that, the effect of an individual's aversion to risk on various solutions in conflict problems, as expressed in his (her) utility function, must be considered. Those kinds of incomplete information make decision maker Bayesian, since it is often impossible to get correct information for building a decision making model. In Baysian point of view, this paper represents an analytic frame for guessing and learning opponent's attitude to risk for getting better reward. As an example for that analytic frame. 2 persons'bi-matrix game is considered. This example explains that a bi-matrix game can be transformed into a kind of matrix game through the players' implicitly cooperative attitude and the need of arbitration.

Following rapid development of software and hardware technologies and increasing enhancement in arithmetic capability, there are more and more content that can be accommodated and processed in video games, which is also increasingly complex and fine. Cutscene as a main narrative method have been developed, which have become necessary to express some key plots and important scenarios in games. Good cutscene can strengthen engagement of players with virtual world in games and make players share affection and sorrow with roles in games; while badly-designed cut-scene or overused cut-scene will impair immersion of players and affect players' gaming experience; for this reason, developers should not continue cut-scene design just from opinions of designers nor make players passive receivers, instead, they should reduce as much as possible interruption by cut-scene to players' immersion and grant players with better immersion. After all, only designs depending on demands and preferences of players by having some knowledge of impacts of cut-scene on players' immersion can be accepted by players.

This study has focused to identify what kinds of psychological state are most closely related in players experiencing flow while playing game. This study constructs a conceptual model of flow for game players by conducting a survey to 303 online game players. The results indicate that the state of flow was reached when players may gain opportunities for having high self-efficacy as they accomplished tasks. At the same time, it indicate that the higher cognitive performance and self-esteem was able to enhance the higher flow experience while playing a game. This study provides both practical and theoretical implications on how to increase players' flow by providing critical psychological states in the game.

Online games have become the focus of entertainment and multimedia industries as the developments in computer technologies are accelerated and the use of the Internet diffuses broadly. In spite of such growth of online games, academic discussions regarding online games are relatively limited. This research examines several factors that affect player loyalty to online games. In this research, the loyalty is classified into two categories, the behavioral loyalty measured by the intensity, volume, and frequency of use, and the cognitive loyalty measured by the degree of immersion in online games. In this research, an integrated model to explain and predict player loyalty to online games in proposed. Two studies are conducted to test to research model. Throughout analyzing 334 respondents, the first study finds that the impulsive personality of individual players significantly affects both behavioral loyalty and cognitive loyalty. Additionally, it finds that, whereas the behavioral loyalty is influenced by the convenience of online game playing, the cognitive loyalty is influenced by the motive of game playing and the playfulness of games. The second study finds that the behavioral loyalty differs across demographic differences of players (age and occupation), preferred online games of players, and online game playing locations, but the cognitive loyalty differs across only age differences of players. This research has opened a forum for social awareness about the online game culture, provided information to guide online game producers to prepare customer-oriented online games, and created a foundation for academic research on online game industry.

In this study, an investigation was conducted into the influencing factors for the learning motivation of players in the game, including experience, vicarious experience, the need of achievement, the need of power, and mastery motivation. Then, a discussion was conducted regarding the role played by learning motivation, learning performance, and satisfaction with continuous use. A survey was conducted with 519 players, most at the intermediate gaming level in . As demonstrated by the results of this study, experience, vicarious experience, the need of power, and the mastery of motivation have significant positive association with the players' motivation of learning the game. Learning performance and satisfaction have a positive impact on the continuity of use. Additionally, the correlation between the need of achievement and learning motivation is insignificant. Overall, the research results confirm the significance of the social-cognitive theory relative to the learning motivation. Players began to transform, satisfied with their achievements in the game, as well as gradually evolving toward self-improvement to achieve satisfaction. It offers a new explanation and crucial reference for mastering the gaming trend among the contemporary players.

If we analyze games and game communities which are mostly consumed by the young, we can get the meaningful analysis result of youth culture. The content analysis and the discourse analysis methods were used in this study since the relationship between media and culture was exquisitely reciprocal. The object of analysis is the domestic community of the simulation game, Sims 2, which reflects the identities of the game players. I was searching for the social and cultural meaning of the game activities, and could find the content's characteristics of 'Sims 2' players' discourses. The results showed that the game media has social and cultural significance by providing the players a self-realization, identity workshop, virtual identity that diverges from their own ones with an alternative sex, constructing a cultural property with the involved game players, and increasing their virtual consumption and self-examination of antisocial behaviors in the game.

In this paper, we analyze the immersion effects according to the level of map in adventure game. Computer games are actively enjoyed by many people around the world. Game players have frequently experienced the immersion which is an important aspect to be attained from games. However, it is not clear what immersion is and what kinds of factors influence to immersion. Nonetheless, in recent many researches, the elements of humanities and fun were found as factors of immersion in various digital contents such as game, virtual reality, cinema and etc. Therefore, today's games are developed on the basis of the humanities and fun theory that many researchers have been studied for a long time. In games, the balance of the level of map is related with immersion. Hence, it is important to know how the map patterns of game affect immersion of players. In this paper, we developed a 3D survival adventure game named by "1 Hour" using Unity3D in order to simulate how map patterns affect immersion of players. We also analyzed the relationship between the level of map and immersion using the game.
