An online game is popular topic due to the increased total online game market volume nowadays. Even though many studies on an online game are released, most studies have used survey method that reveal only section of the situation like a snapshot. For this reason, previous studies have a little limitation that does not show dynamically changing issues like a product life cycle and change in customer's satisfaction. Because of this, we researched on an online game with the system dynamic model which can show dynamic simulation to analysis time series data. We chose MMORPG (Massively Multi-play Online Role Playing Game) in sort of an online game because it has many absorbing factors and enthusiastic users. We assumed that the game developer is ready for updated version game and release that periodically and focused on dormant users who used to be enthusiastic about MMORPG and designed simulation model which analyze how to influence of update and CRM strategy on users. The simulation results showed that the update has positive influences to gather new users and hold established users and CRM strategies help to prevent dormant users from transferring to rivals to offer them re-absorbing factors. Through this study, we confirmed importance of update on a online game and suggested the necessity to introduce CRM strategy in an online game market.

Online games are virtual space where it connects individual users through network connection to offer enjoyment of play games and game developer who service online games have to develop new contents and provide them to users to extend life of their service. Typically, in order to update new contents, all service companies have maintenance schedule to stop the game service for a while to update both server and client applications. Usually this process takes quite amount of time and users do not have any other choice but disconnected from server and wait until it is over. The purpose of this thesis is to describe the advantages of new design system which will allows users to continue to play the game even during the update. The main focus of this design is to make users feel more convenience in online gaming experience by move client from previous server to new server while users are still playing. If they can to connect current client with new server without any certificate validation process while users information from the client can automatically pass through to the new server, users may not need to experience maintenance for new contents update.

The MOBA game is updated every year with a new season, the new season update brings fun to the game users and also makes them feel unfamiliar with the new gameplay. In order to let game users better adapt to the new season, this study will extract the new season balance evaluation factors. Firstly, we used one-on-one review to collect the unbalanced factors that game users had encountered at the beginning of the new season of the MOBA game, and secondly, we organized the collected review data into a questionnaire and conducted a survey. The first step of the experiment was to filter out the lower factors through exploratory factor analysis and extract the balance evaluation factors of the MOBA game new season. The second step of the experiment was to examine the correlation between the factors through confirmatory factor analysis, as well as to confirm the appropriateness and explanatory value of the factors. The analysis resulted in "Game character experience", "Game view's expression", "Game level", and "Composition of the game setting" are the four factors. Finally, through correlation analysis, the most relevant factor for game satisfaction is the "Game character experience", and each factor is correlated with each other.

이 논문에서는 블록체인을 이용해 게임 변수들 (게임 난이도, 아이템 강화확률 등)을 사용자들이 직접 공정하고 투명하게 업데이트하는 게임 시스템을 제안한다. 일례로 소개하는 이더리움 기반 미로 탈출 게임은, 최초의 블록체인 기반 미로 게임이며 블록체인을 통해 난이도를 조절하는 최초의 시도이다. 이 시스템에서는 난이도 함수가 사용자들이 매매한 미로 벽의 수량을 반영해 난이도를 계산한다. 게임 관리에 블록체인을 사용하는 것은 인적 경제적 자원을 절약할 뿐 아니라, 난이도 및 아이템 강화확률을 일방적으로 조작하는 게임 개발자의 불공정한 관행도 방지된다. 누구도 비밀스럽게 미로, 승자, 난이도를 조작할 수 없기 때문이다.

본 연구의 목적은 시장에 출시된 온라인 게임의 운영과정에서 오류를 수정하고 게임성능을 제고하기 위해 제공하는 콘텐츠 업데이트 또는 패치서비스가 실질적으로 게이머의 플레잉 시간에 영향을 미치는지 여부를 계량적으로 분석해 보는 데에 있다. 이를 위해 온라인게임 개발회사가 게임콘텐츠와 관련하여 추가하는 콘텐츠 업데이트를 두 가지 유형으로 구분하여 업데이트 후 플레잉 시간에 통계적으로 유의한 영향을 미치는지 여부를 회귀분석을 이용하여 분석하였다. 분석 결과, 콘텐츠 업데이트 외에 추가적인 독립변수로 설정한 출시 후 경과시간은 플레잉 시간 변동에 음의 유의한 영향을 미치는 것을 나타났지만, 새로운 게이머들을 유인하고 기존 게이머들의 플레잉 시간을 증가시키기 위해 제공하는 콘텐츠 생성이나 조절은 플레잉 시간 증가에 유의한 영향을 미치지 않은 것으로 나타났다. 연구결과가 제시하는 게임 디자인 측면에서의 시사점을 결론으로 제시하였다.

We propose guidance laws based on a pursuit-evasion game. The game solutions are obtained from a pursuit-evasion game solver developed by the authors. We introduce a direct method to solve planar pursuit-evasion games with control variable constraints in which the game solution is sought by iteration of the update and correction steps. The initial value of the game solution is used for guidance of the evader and the pursuer, and then the pursuit-evasion game is solved again at the next time step. In this respect, the proposed guidance laws are similar to the approach of model predictive control. The proposed guidance method is compared to proportional navigation guidance for a pursuit-evasion scenario in which the evader always tries to maximize the capture time. The capture sets of the two guidance methods are demonstrated.
