This study aims to analyze the structure and characteristics of the domestic online game industry using network analysis. In particular, two-mode network analysis is employed to measure the network structure, centrality, and cluster for two types of online game platforms, online games and mobile games, from 1996 to 2014. We also conduct a dynamic analysis to capture the structural changes in the ecosystem by internal and external environmental changes before and after turning point for each online game platform. It is revealed that the online game econsystem has the higher number of clusters and higher concentration ratio than those of mobile game ecosystem. In dynamic analysis, both platforms exhibit similar trends over time with the increasing number of clusters, enlargement of largest cluster's size, and decreasing concentration ratio. This study is expected to provide fruitful implications for strategic decision making of online game companies and policy making for the online game industry.

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.
