게임의 장르는 플레이어에게 주로 제공되는 플레이 방식에 따라 액션, 어드벤처, 롤플레잉, 시뮬레이션 등으로 나뉘며, 각 장르에서 게임은 다양한 형태의 밸런싱을 갖는다. 이 중 대전 격투 게임은 액션 장르의 한 형태로서, 단순해 보이지만 여러 가지의 복합적인 밸런싱 요소들을 가지고 있으며, 비교적 빠른 기간에 독립 장르로 확립되고 백여 편에 이르는 게임이 제작되어 초기의 불안정한 형태에서 최근의 안정된 형태에 이르기까지 다양한 게임 밸런싱 구조를 확인할 수 있다. 게임 밸런싱은 게임 내의 여러 구성요소 간 불균형을 해소하여 플레이어가 게임이 제공하는 모든 콘텐츠를 고루 이용하도록 유도하고, 그 과정에서 게임 플레이의 재미가 유지되는 것을 목표로 한다 또한 진행과정에 있어서 당위성을 부여하고, 조작에 따른 효율성을 증대시키며, 플레이어의 감정이입을 유도하여 몰입감을 향상시키는 등 게임의 완성도에 대한 평가와 수명(흥행)에 절대적인 영향을 미치는 중요한 요소로 인식되고 있다. 따라서 본 논문에서는 주요 대전 격투 게임의 사례 분석을 통해 해당 장르의 발전모습과 그 과정에서 수립된 밸런싱 모델을 파악하므로써, 타 장르로의 확대 적용 가능성을 연구해 보고자 한다.

One of the most important reasons for using online game is intrinsic motivation which relates the drive to perform a behavior for perceptions of pleasure and satisfaction from the behavior itself. Therefore, most studies for using online game have been based on theories for intrinsic motivation such as flow. However, such theories have some limitations for explaining social aspects of online games such as Massively Multiplayer Online Role Game (MMORPG), which provides a society for game players by using a virtual space for playing games so called 'persistent world'. Adaptive structuration theory (AST) is one of trying to capture the change of using IT due to social interactions between users and system. In order to explain online game players' behavior considering social interaction, we suggest a research model based on AST. Our model aims to investigate the relationship between appropriation which is determined by faithfulness of appropriation (FOA) and consensus on appropriation (COA) and performance which is represented by the relationship among perceived winning, flow, and intention of reuse. An empirical test of our model for 125 MMORPG users which is analyzed by Partial Least Square method shows very satisfactory and interesting results. While hypotheses suggested in our model are supported, the influence of COA on game performance is shown to be stronger than that of FOA.

RPG게임에서의 맵은 단순한 캐릭터들의 이동이나 활동을 위한 무대를 제공하는 것뿐만 아니라 몬스터와 NPC등 게임의 모든 요소가 혼합된 월드로서 작용을 한다. 그러나 맵과 맵에 따른 몬스터의 설계는 게임이 어느 정도 개발된 후에 테스트를 통해서 밸런스를 맞춰가야 하는데 이를 위해서는 개발기간이 추가되는 문제가 발생하게 된다. 본 논문에서는 게임기획초기에 맵과 맵에 따른 몬스터의 배치를 게이머의 성향에 따라 설정함으로써 특정 맵만을 사용함에 따르는 비효율적인 맵 사용을 방지할 수 있는 맵 시뮬레이터를 설계 구현하면서 연구한 결과를 기술한다.

This paper measures and compares the traffic of a series of Massively Multi-player On-line Role Playing Game (MMORPG). The purpose of this analysis is to characterize the MMORPG traffic and compare the traffic characteristics of those games caused by the game structure difference between 2D and 3D environment. The target game is 'Lineage I' and 'Lineage II' which represent world's largest MMORPGs in terms of the number of concurrent users. We collect about 280 giga bytes and 1 tera bytes of packet headers, respectively. We compare packet size, packet inter-arrival time and bandwidth usage of these two games. The MMORPG traffic consists of two kinds of packets: client-generated upstream packets and server-generated downstream packets. We observe that the upstream packet size of payload has grown from 9 bytes to 19 bytes, while the average payload size of downstream packets has grown from 37 bytes to 318 bytes. This asymmetry of growing rate is caused by 3D game structure. Packet inter-arrival time becomes shorter from average 2 milliseconds to 58 microseconds. Bandwidth consumption per client has grown from 4 kbps to 20 kbps. We find that there is a linear relationship between the number of users and the bandwidth usage in both case.

This study investigated player responses to microtransactions in freemium Massively multiplayer online roleplaying games (MMORPG), specifically focusing on the game LostArk using English language review data. To this end, structural topic modeling was employed and the following six microtransaction-relevant topics were identified: microtransactions, developer issues, real money trade (RMT), random number generator (RNG) upgrade system, game content, and collectibles & adventure. The first four topics were classified as being "not recommended". However, the proportions of microtransaction-related topics were relatively lower than the other topics. Additionally, this study did not extract keywords related to unfairness and unethical issues in previous microtransaction research. The last two topics, game content, and collectibles & adventure were "recommended" topics, indicating positive functions of microtransactions such as enhancing the game experience by purchasing virtual items. Moreover, it was found that players who do not engage in microtransactions can still be satisfied through continuous game content updates. Additionally, an examination of the interaction effect between time and recommendation status revealed that while the frequency with which the six microtransaction-related topics were mentioned increased over time in the reviews, the ratio of recommendations to non-recommendations varied differently. This study contributes to game-related research by revealing players' authentic opinions on microtransactions in freemium MMORPGs, thereby providing practical implications for game companies.

With the recent popularity of smartphones, many games are being developed on mobile-based platforms. As a result, it has brought about many changes in the way mobile game is developed. Especially mobile platforms, which are divided into Android and IOS, can now be applied to each platform without additional development through cross-platform. This means that it is necessary to move away from the method of developing each using separate development tools and implement the development process through cross-platform unique features. In this paper, we studied various methods to increase the productivity and quality of game development for the development of mobile games, and a formal framework considering the development process was developed. The framework consists of process, development domain, and platform support parts, each playing its own role. Items of the detailed framework must be reflected so that detailed response data for efficient application of game development can be established in actual mobile game development. The framework was developed by approaching it from two domains, the need for a framework and the framework implementation of key item response data.
