게임 플랫폼의 고도화와 게임 구현 기술의 발전을 통해 이루어지고 있는 개발 환경의 효율성 제고를 통해 이전에 게임의 구현 자체에 소요하는 시간을 게임 콘텐츠의 질적 향상을 위해 투입할 수 있는 여건이 형성되고 있다. 본 논문은 게임에서 등장하는 NPC가 보다 사실적인 추론을 통해 플레이어를 추적하도록 지정하는 알고리즘을 고수준의 카테고리로 구분하여 구현하여, 개발 과정에서의 NPC 구현에 효율성을 제고하는 기법을 제안한다. NPC가 플레이를 추적하는 스토리를 기반으로 하는 게임에서 NPC가 플레이어의 위치에 도달하기 위한 길찾기 알고리즘은 필수적이다. 일반적으로 사용되는 최단 거리 길찾기 알고리즘인 다익스트라(Dijkstra)의 경우, 효율적이지만 플레이어가 NPC의 경로를 예측 가능할 수 있기에 게임의 재미 향상에 걸림돌이 되는 단점이 있다. 본 논문에서는 최단 거리 길찾기를 구현하면서 다양한 게임 스토리 상의 설정으로 지정할 수 있는 다양한 방법론을 연구하였으며, 이를 구현하기 위한 고수준 길찾기에 대한 방법을 제시한다.

With the development of hardware and 3D graphic technologies since the 1990s, video games have been evolving in the direction in which they wholly pursue illusions and movie formats, and thus they are considered to be media centered on spectacles. However, video games, due to their inherent characteristics, cannot be transparent media like the existing spectacular entertainments centering on optical illusions. In their structure, there can be found elements that continually disillusion players from visions. Strictly speaking, players are not lost in visions, but are kept a certain distance from internal contexts. Games rely not on illusion but on contracts with players which are similar to a kind of convention, clearing internal imperfections. This paper aims to identify and analyze disillusioning elements and discuss theatrical contacts between players and games. The purpose of this paper is to reconsider the awareness of video games as a spectacle entertainment and to help discover future directions for game culture.

As the online game market grows, the use of game bots is causing the most serious problem for game services. We propose a harvest coordinate analysis model to detect harvesting bots among game bots of the Massively Multiplayer Online Role-Playing Games(MMORPGs) genre. The proposed model analyzes the player's harvesting behavior using the coordinate data. Game bots can obtain in-game goods and items more easily than normal players and are not affected by realistic restrictions such as sleep time and character manipulation fatigue. As a result, there is a difference in harvesting coordinates between normal players and game bots. We divided the coordinate zones and used these coordinate zone differences to distinguish between game bot players and normal players. We created a dataset with NCSoft's AION log and applied it to a random forest model to detect game bots, and as a result, we derived performance with a recall of 0.72 and a precision of 0.92.

Massively Multiplayer Online Role-Playing Games (MMORPGs) are played by millions of people around the world. Within MMORPGs, players explore, solve mysteries, craft items, battle against dungeon or raid bosses, or compete against other players, all while using a variety of information and information behaviors. Role-players in MMORPGs develop identities and engage in interactive storytelling with other role-players as their characters. An ethnographic approach combining overt participant observation and engagement, semi-structured interviews, and artifact collection was used to explore and describe the social information behaviors of role-players through the lens of the theory of information worlds. The social types evident in the role-playing community in WildStar, a science fantasy-themed MMORPG, are closely interrelated to and differentiated by social norms and information values that dictate acceptable characters, stories, character actions, and appropriate lore sources as well as how to role-play without violating the boundary between in- and out-of-character information worlds. Role-players maintained the in-character and out-of-character boundary using a set of specific information behaviors to enable engaging and immersive role-playing experiences. Implications of the findings for the theory of information worlds as well as potential applications of role-playing and MMORPGs are also discussed.

Game balance settings are crucial to game design. Game balancing must take into account a large amount of numerical values, configuration data, and the relationship between elements. Once released and served, a game - even for a balanced game - often requires calibration according to the game player's preference. To achieve sustainability, game balance needs adjustment while allowing for small changes. In fact, from the producers' standpoint, game balance issue is a critical success factor in game production. Therefore, they often invest much time and capital in game design. However, if such a costly game cannot provide players with an appropriate level of difficulty, the game is more likely to fail. On the contrary, if the game successfully identifies the game players' propensity and performs self-balancing to provide appropriate difficulty levels, this will significantly reduce the likelihood of game failure, while at the same time increasing the lifecycle of the game. Accordingly, if a novel technology for game balancing is developed using artificial intelligence (AI) that offers personalized, intelligent, and customized service to individual game players, it would bring significant changes to the game production system.

The purpose of this paper is to examine the temporal and spatial characteristics of mobile games through Mikhail Bakhtin's chronotope concept in order to examine the changes of mobile games and gaming. Based on chronotope, a concept that refers to the inner relation between time and space reproduced in the novel, I examined the inner relation between the space - time experience in the mobile game platform and the reconstruction of the mobile game text. The mobile game builds the present-here world based on the player's will while superimposing the act of playing through the mixed platform of existence based on the player with the time and space of everyday life. The chronotope of a mobile game with players as platforms is created in the current space of now-here rather than connecting to the virtual world. In this paper, I review the role of chronotope reproduction in mobile games, focusing on role-playing games and location based games. In the mobile role-playing game, an unhistorical chronotope appears in which the player has a loose sense of distance around the automatic combat system, while the narrative and relational experience is weakened. In a location-based game, a chronotope of player-driven generation that generates amusing meanings through the overlap of the virtual world and the real world appears.

This study explores the effects of 'save and load' on game storytelling. In video games, a player can control the game she plays by repeatedly saving and loading game data until she reaches her intended goal. As a consequence, a player can manage the game time. In this article, game time is divided into two parts; play time and story time in order to examine how player's intentions are reflected in game storytelling. This is what distinguishes game narrative from others in that the player generates her own story by saving and loading.

The purpose of this study is to analyze the characteristics of traditional art expressions in recent Chinese online games, which are now most popular in Chinese game market. Designing the MMORPG game character reflecting users' psychological preferences for aesthetic characteristic of the traditional Chinese culture allows the users to feel more visual satisfaction while they are enjoying a game. The selected characters for this analysis were chosen from the traditional myth chivalry game to utilize the traditional art expressions that are peculiar in Chinese MMORPG. The analysis was conducted within the context of an ideal character figure and operation, and social nature reflecting a personal user. This analysis suggested the representation technique reflecting traditional clothing, color, and life style, and the reconstruction of subject matter, and the development of the characteristics of ideal group character. Even though Chinese MMORPG history is short, this study will help the user understand more effectively the identity of the myth martial MMORPG game in connection with the Chinese traditional culture and art. And this study will also increase the user's satisfaction of the Chinese online-game.

In computer games, the level design and balance of characters are the key features for developing interesting games. Level designers make decision to change the parameters and opponent behaviors in order to avoid the player getting extremely frustrated with the improper level. Generally, opponent behavior is defined by static script, this causes the games to have static difficulty level and static environment. Therefore, it is difficult to keep track of the user playing interest, because a player can easily adapt to changeless repetition. In this paper, we propose a dynamic scripting method that able to maintain the level designers' intention where user enjoys the game by adjusting the opponent behavior while playing the game. The player's countermeasure pattern for dynamic level design is modeled using a Gaussian Mixture Model (GMM). The proposed method is applied to a shooting game, and the experimental results maintain the degree of interest intended by the level designer.
