This study looked into how to carry out sacrifices for intra-game cooperation in becoming a high-level player. The results are as follows. First, the way players behave is dependent on their resources(scores). Second, the higher the player's score, the more praise cards were given to dealers. Third, high-scoring players have taken on a role of "sacrificing the self to serve the many" by voluntarily playing the role of healer, leading the team to set the rules and consequently reducing the risk of a probable role conflict within the team.

This study aims at empiricallly designing method to increase player's play capability through determining of the relations of player's behavior pattern and emotion factors when having gameplay experiences in MMORPG. For modeling emotion factors on gameplay, Our preliminary studies are considered in the process of rule-based systems on cognitive science approach. These study estabilished game architecture process applied of player's cognitieve emotion reactions in specific situation of role playing games that have most noticeable interaction with players based on quest system. This approach is expected to extend instant responses, which can be controlled behind all of anti-main behavior pattern and main behavior pattern in game playing. Therefore, such study is meaningful that is proposed the analysis framework of player's emotion factors to design game playing capability in game interactions.

The study of classifying gamer types or analyzing the characteristics of gamers is a field of interest for data analysis researchers. From the past to the present, much research has been done on gamer categorization and gamer analysis. However, most studies use surveys or bio-signals, which is not practical because it is difficult to obtain large amounts of data. Even if the game log is used, it is difficult to analyze the psychology of the gamer because the gamer is categorized and analyzed by extracting only statistical values. However, if we can extract the cognitive psychology information of the gamer from the basic game log, we can analyze the gamer more intuitively and easily. In this paper, we extracted eight cognitive psychological features representing the behavior and psychological information of the gamer using Crazy Dragon's game log, which is a mobile Role-Playing-Game (RPG). In addition, we classified gamers based upon cognitive psychological features and analyzed them using eight cognitive psychological features. As a result, most gamers were highly correlated with one or two types.

Identity theft happens frequently in popular MMORPG(Massively Multi-player Online Role Playing Games) where profits can be gained easily. In spite of the importance of security about identity theft in MMORPG, few methods to prevent and detect identity theft in online games have been proposed. In this study, we investigate real identity theft cases of an online game and define the representative patterns of identity theft as the speedy type, cautious type, and bold type. We then propose the automatic identity theft detection model based on the multi-class classification. We verify the system with one of the leading online games in Korea. The multi-class detection model outperforms the existing binary-class one(hacked or not).

Among the various security threats in online games, the use of game bots is the most serious problem. Previous studies on game bot detection have proposed many methods to find out discriminable behaviors of bots from humans based on the fact that a bot's playing pattern is different from that of a human. In this paper, we look at the chatting data that reflects gamers' communication patterns and propose a communication pattern analysis framework for online game bot detection. In massive multi-user online role playing games (MMORPGs), game bots use chatting message in a different way from normal users. We derive four features; a network feature, a descriptive feature, a diversity feature and a text feature. To measure the diversity of communication patterns, we propose lightly summarized indices, which are computationally inexpensive and intuitive. For text features, we derive lexical, syntactic and semantic features from chatting contents using text mining techniques. To build the learning model for game bot detection, we test and compare three classification models: the random forest, logistic regression and lazy learning. We apply the proposed framework to AION operated by NCsoft, a leading online game company in Korea. As a result of our experiments, we found that the random forest outperforms the logistic regression and lazy learning. The model that employs the entire feature sets gives the highest performance with a precision value of 0.893 and a recall value of 0.965.

Game artificial intelligence is usually used to provide intelligent and adjusted game environment for user. Previously, it was used for Non-player character(NPC) playing a role of a company or an enemy through collecting and analyzing a user's behaviour. However, it was just mimicking the user's behavior. This paper introduces a method to change game environment by analyzing a user's game behavior. Game behavior data has been used to understand user's game preference. Also, the user's preference was used to provide more active game environment by reflecting decision of geographical features, items and distribution of NPC. For experiment of the suggested method, we utilized a real 2D action game and confirmed the game environment which changing properly according to the user's game play.

In this paper we propose a method to analyze user's motion as a game command, and implement a sports serious game applied the motion analysis method as a command interpreter. Recently, various contents platforms appear in industrial market, the computer game contents plays an important role in these emerging platforms as a killer contents. The computer game has enough values as an independent major cultural product, moreover it has the potential to be applied in various other fields such as education, healthcare, training, and so on. It could motivate users to do something continuously, and it could also support an immersive environment in a certain special game contents such as VR game. The Serious game 'ChoDeungGangHo', implemented in this paper, is the sensory healthcare serious game based on 3D run game and fitness game. It is designed for user to train the various exercise element by just playing the game, and it also supports the user management system and the linkage of social media. We proposes the sensory serious game 'ChoDeungGangHo' as a model of commercial serious game.

An important application domain for online services is an interactive, multiplayer game. in recent, many increase of users that use on-line services through networks have caused a heavy load to the server. In this paper, we propose a MMORPG distributed game server using 2Layer-Virtual Cell. Our method provides more effective solution of MMORPG distributed game server for large numbers of users.

컴퓨터 게임은 많은 정보의 집약체로 화면 내의 인터페이스와 사운드를 통하여 현재 아바타에 대한 상태 및 게임의 상태를 사용자들에게 전달해 된다. 이러한 정보전달은 사용자 인터페이스로 불리며, 사용자들이 보기 편하게 화면상에 표시하게 해준다. 화면으로 사용자들에게 아바타의 현재 상태를 표시해주기 때문에 게임에서 매우 중요한 역할을 하게 된다. 또한 게임의 배경에 맞게 사용자 인터페이스를 설계하였을 경우에는 게임의 복잡도를 낮추거나 게임에 대한 몰입도를 증가시켜줄 수 있다. 특히 역할 게임에서의 사용자 인터페이스는 현재 게임 캐릭터의 상태, 체력, 데미지 등 많은 정보를 사용자에게 전달하여야 하며, 이러한 정보를 토대로 사용자가 게임에 좀 더 몰입하고 게임을 쉽게 진행할 수 있도록 도와주는 중요한 역할을 하게 된다. 본 논문에서는 역할 게임에서의 사용자 인터페이스를 적용한 방법에 대해 설명한다.

The format of game play varies depending on the priority of game design components by genre. In this study, in order to quantitatively derive the priority of game design components by genre, 6 game design components and 6 genres were extracted through prior research on game design components and genres, and then the research model was designed, and priorities were derived through AHP. Feedback system in action games, story in adventure games, mechanics in role-playing games, mechanics in simulation games, feedback system in table games, and mechanics in puzzle games were highly prioritized.
