Game bot playing is one of the main risks in Massively Multi-Online Role Playing Games(MMORPG) because it damages overall game playing environment, especially the balance of the in-game economy. There have been many studies to detect game bot. However, the previous detection models require continuous maintenance efforts to train and learn the game bots' patterns whenever the game contents change. In this work, we have proposed a machine learning technique using the self-similarity property that is an intrinsic attribute in game bots and automated maintenance system. We have tested our method and implemented a system to major three commercial games in South Korea. As a result, our proposed system can detect and classify game bots with high accuracy.

Client- server interaction in a massive multi-player online role-playing game(MMORPG) is usually made via network-message Passing. Since the game contents and elements in such MMORPGs are consistently evolved, messages need to be added, deleted, or modified accordingly. Therefore, game programmers are repeatedly required to write new programs or at least modify existing programs. The XML-based message definition system introduced in this paper facilitates the addition and modification of messages for game interaction ; it not only allows programmers to save a considerable amount of time for modifying existing messages or adding new messages but also relieves them of a serious burden of programming bugs. In addition, this system can be used for general client-server applications.

China's online games have been developed a decade, the online game development is very fast. The last monitoring from "gameScan$^{TM}$" shows that there are 6 local manufacturing MMORPG games in the top 20 in march 2010 of china.Through research top 4 MMORPG games, their graphic content is too similar. All of them are the subject of Chinese Martial-Arts and Chinese Mythology, the graphic design elements all from China's traditional culture. This phenomenon will be two defects, the first if the design follow the trend, it can reduce the risk of failure, but it'll lack of competitiveness also. The second is it can meet the needs of Chinese culture for the game players in china, but the complex Chinese mythology and the culture of Martial-Arts are not easy to be accepted for foreigners. There are many European and American games failed in China, because of the differences cultural, the Game players can't understand the history, religion and culture. so, we can get some experience from the successful game cases of Korea and Japan. Use of common cultural elements combined with some Chinese traditional culture to create a new fantasy world. And try some now contents about future or science fiction.

The purpose of this study is to analyze the specific mimesis types of common character costumes in MMORPGs, which have stories that are very similar in structure to ancient myths and fantasy novels. As the subject of the research I have selected "Diablo 3" created by the American video game developer, Blizzard Entertainment Images of 5 characters, for both genders - Barbarian, Witch Doctor, Monk, Demon hunter, Wizard - were compiled for a total of 10 images, and these images were compared to popular archetypes in mythology, religion and literature. analyzed them separately according to the mimesis type. For this study, Articles and books containing the Aesthetics, Mimesis and Digital culture were researched in order to study the costume features and the Mimesis types and compare them to the costumes in the MMORPG. Firstly, the character Barbarian is a successor of the barbarian character of the previous product. The outfit worn by the game figure is based on the common images expressed in the movie . The makers created an analogous-imitation mimesis by replicating the image in an exaggerated and grand form. Second, the character Witch Doctor derived its motif from the Voodoo cult, and was expressed in analogous-imitation mimesis, using the very shades and patterns used in real life. Third, the character Monk, blending the image of a priest in Eastern Europe and images of its oriental counterparts, was expressed in transposition-diversion mimesis. Fourth, the Demon Hunter took the source of its inspiration from the image of a Witch hunter in the medieval times. The game character has a sharper sleeker figure than its model, and uses more acute shapes and darker gloomier colors expressed in an analogous-imitation mimesis. Finally, the character Magician took a formless character and expressed it in transposition-diversion mimesis taking as its basis some fantasy novels.

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).

As game item trading becomes more popular with the rapid growth of online game market, the market for trading game items by cash has increased up to KRW 1.6 trillion. Thanks to this active market, it has been easy to turn these items and game money into real money. As a result, some malicious users have often attempted to steal other players' rare and valuable game items by using their account. Therefore, this study proposes a detection model through analysis on these account thieves' behavior in the Massive Multiuser Online Role Playing Game(MMORPG). In case of online game identity theft, the thieves engage in economic activities only with a goal of stealing game items and game money. In this pattern are found particular sequences such as item production, item sales and acquisition of game money. Based on this pattern, this study proposes a detection model. This detection model-based classification revealed 86 percent of accuracy. In addition, trading patterns when online game identity was stolen were analyzed in this study.

The growth speed of the industry of national smart phone game service has become faster and the its economical and cultural effect has increased steadily these days. The DB design for data perpetuation in C/S MMO which has accumulated data a lot and many simultaneous plays like smart phone games is very important. This paper, mindful of the operation and the scalability suitable for android OS, by utilizing RDBMS, enabling very short, many transactions, their complexity, and a large amount of game data process, suggests fully-qualified MMORPG game service architecture design techniques widely available for more than online game industries.
