Game agents which are behavioral agent for game playing are a crucial component of game satisfaction. However it takes a lot of time and effort to create game agents for various game levels, environments, and players. In addition, when the game environment changes such as adding contents or updating characters, new game agents need to be developed and the development difficulty gradually increases. And it is important to have a game agent that can be customized for different levels of players. This is because a game agent that can play games of various levels is more useful and can increase the satisfaction of more players than a high-level game agent. In this paper, we propose a method for learning and controlling the level of play of game agents that can be rapidly developed and fine-tuned for various game environments and changes. At this time, reinforcement learning applies a policy-based distributed reinforcement learning method IMPALA for flexible processing and fast learning of various behavioral structures. Once reinforcement learning is complete, we choose actions by sampling based on Softmax-Temperature method. From this result, we show that the game agent's play level decreases as the Temperature value increases. This shows that it is possible to easily control the play level.

The interrelation between abusive game designers and players are revealed and considered as one of the game arts by Miguel Sicart. This study is based on the frame analysis of Ervin Goffman. The player centered game design, in the case of a digital game, is penetrated into the frame, and player's experience and game frame at the same level can be assumed as positive down-keying. Conversely, confusion of the game is experienced by the players and perceptions about the games are required. The term of Miguel Sicart, generated the abusive game design in the view of the game art, considers both common game and design of the game, respectively. Nevertheless, the abusive game design refreshes the reflections of players in a game and presents possibilities of bridging the designs of standard games through the techniques and devices.

The aim of this paper is to find out semiotic interpretation in digital gameplay and define layers of meaning which is provided by a game designer and a player. The primary author of the digital game is a game designer; however, to accomplish the whole meaning of the digital game, there must be a player's action. In digital games, the game designer leads to player's action and the player progresses the game at her desire. During the gameplay, each of the intention clashes and coincides through the semiotic interpretation. It can be classified under five sections that represent the game designer, the player and the game text.

Computer games must keep the user immersed for fun. According to the immersion theory, maintaining the user's immersive state requires a continuous balance of game skill level and game difficulty level This study proposes a game skill estimation method of 9th grade that can be applied to a casual action game that can assume a zero-sum game, and additionally proposed a difficulty guessing method. The proposed methods can be implemented quickly and easily because it is a method determining by conditional mathematical expressions. Experiments on the accuracy of the proposed methods for the customized Pac-Man game show that the accuracy of the skill level was 1.2 grade as the difference on the average and the accuracy of the game difficulty level was 1.81 grade the difference on the average. The results show that the proposed methods are accurate enough to be applied to casual action games satisfying the zero-sum condition.

온라인 게임에서 불법 프로그램을 이용한 게임 봇을 대규모로 운영하는 전문 사설 업체를 속칭 '작업장(Gold Farming Group, GFG)'이라고 부른다. 기존에 작업장에서 운영하는 게임 봇은 24시간 쉬지 않고 반복적인 파밍을 통해 수익을 극대화하는 전략을 취했으나 최근 온라인 게임의 계정 가입이 쉬워지고 무료 플레이가 보편화되면서 개개의 게임 봇 계정이 수행하는 플레이 시간이나 취득 재화 수준을 낮추는 대신 수만 개의 계정을 번갈아 가며 운영하는 방식으로 변하고 있다. 이로 인해 플레이 활동 패턴에 기반한 기존의 탐지 모델들이 점차 무력화되고 있으며 진입 초기에 게임 봇을 빠르게 탐지하고 제재하는 방안이 점차 중요해지고 있다. 우리는 게임 봇을 조기에 탐지하기 위한 방안으로 계정 및 캐릭터의 이름이 갖는 특성을 활용한 게임 봇 탐지 기법을 제안한다. 제안한 기법의 유효성을 검증하기 위해 북미에서 서비스 중인 엔씨소프트의 MMORPG인 '블레이드 앤 소울'의 약 20만 개 계정 정보를 이용해 탐지 성능을 측정하였다. 실험에 의하면 캐릭터 이름에 대해 간단한 나이브 베이즈 분류기를 적용하는 것만으로도 AUC 기준으로 약 0.901의 성능을 기록하였다.

A game designer is the initial design of the quest based on narrative. It is important that to predict game character of play experience to establish these static content. This paper deal with player's affective interaction distinguishing among game characters are perform quest-play based on their characteristic status. To achieve this, First of all, previous studies regarding pre-visualization of narrative structure for other visual media are reviewed. Secondly, it is specified that quest-play experience and player's cognitive behavior. At last, these features of status by character were pre-visualized with QUG(Quest Unit Graph), which could be represented differences in precess of quest-play through analysis on world of warcarft game. Previous research is about of numerical balance in terms of character's achievement, whereas this study is meaningful that is proposed that visual model of quest-play interaction focused on narrative structure to predict game designer's architecture of quest experience.

The purpose of this paper is to identify the significance of heterogeneity in multi-player VR games. Heterogeneity is a concept of multi-player mode that a game uses the immersive VR and non-immersive system at the same time. As immersive VR device has become more commercial, multi-player VR games try to use heterogeneity strategically. is the best example to explain a new phenomenon, so this paper analyses by using a revised and reinforced MDA framework. As a result, we can find heterogeneity concept not only in the separation of player's interface, but also in the division of play patterns and experiences within a game itself.
