Games are usually composed with several units such as monsters, weapons etc.. There are often intransitive relationships between units, like the one among rock, scissors and paper. Intransitive relationships guarantee the variation of strategy choices while playing. But AIs in many games have been ignored intransitive relationships because decision making with those relationships is complex to model. This paper suggests how to use intransitive relationships to modify influence map. With the modified influence map game AI can make a different decision to win the game. With path-finding technique, this paper shows that the modified influence map makes AI's behaviors better.

Considering the topology of hierarchical tree structure, each cluster in WSNs is faced with various attacks launched by malicious nodes, which include network eavesdropping, channel interference and data tampering. The existing intrusion detection algorithm does not take into consideration the resource constraints of cluster heads and sensor nodes. Due to application requirements, sensor nodes in WSNs are deployed with approximately uncorrelated security weights. In our study, a novel and versatile intrusion detection system (IDS) for the optimal defense strategy is primarily introduced. Given the flexibility that wireless communication provides, it is unreasonable to expect malicious nodes will demonstrate a fixed behavior over time. Instead, malicious nodes can dynamically update the attack strategy in response to the IDS in each game stage. Thus, a multi-stage intrusion detection game (MIDG) based on Bayesian rules is proposed. In order to formulate the solution of MIDG, an in-depth analysis on the Bayesian equilibrium is performed iteratively. Depending on the MIDG theoretical analysis, the optimal behaviors of rational attackers and defenders are derived and calculated accurately. The numerical experimental results validate the effectiveness and robustness of the proposed scheme.

This paper aims to explore the glocal storytelling strategy of hero's journey content. Many digital games use hero's journey as a framework. However, it is also true that game storytelling is so common that it is soon recognized as a hero's journey. Therefore, this paper paid attention to the new hero's journey application method of the webtoon . The story created an atypical and Korean character on a typical hero's journey plot. It implements an alternative glocal storytelling aiming at harmony between the region and the world by presenting a regional character on a global universal plot.

For the rapid growth of Chinese on-line game market in this decade, it became more necessary to study Chinese on-line game industry, business strategy, and, especially the behavioral characteristics of on-line game users. In spite of these necessities, there were a few studies on these research fields in China. The current study investigated the relationships among perceived price, perceived quality, the flow, perceived value, and loyalty of Chinese on-line game user. In addition, we tested the influence factors on perceived value and game user loyalty of on-line game user through AMOS method. Results showed that perceived value and game loyalty are positively related perceived price and the flow, the flow and perceived value respectively.

Mobile games have become one of the most important driving forces of the game industry. We focus on the continuous intention to use Chinese mobile games from the perspective of experiential marketing and network externalities. We integrate user experience, network externalities and flow theory into expectation confirmation model and explore the influencing factors of continuous usage intention of Chinese mobile game and propose a research model. Game experience, service experience, perceived enjoyment, social interaction, challenge, perceived number of users and perceived number of peers were employed as independent variables, while flow, perceived value and satisfaction as mediating variables and continuous intention as the dependent variable. After surveying 426 samples, the model is tested with structural equation model. The results reveal that perceived enjoyment significantly positively influences perceived value, flow, satisfaction, and continuous intention. The greater the enjoyment of the game, the greater the satisfaction of the game and the greater the willingness to use it continuously. Game experience has a significant direct effect on continuous intention, which indicates that a better game experience can retain more users. Service experience and perceive number of peers positively influence satisfaction. Another finding is that social interaction and perceived number of users positively influence perceived value and flow, which indicate that social attributes are critical roles for retaining users. Game challenge also positively influences flow. The proper level of challenge is more likely to cause users to enter the state of flow. Flow indirectly influences continuous usage intention through the satisfaction of the game, which indicates that satisfaction is driven by flow experience and further retaining users. Empirical results implied that mobile game companies need to focus on improving user experience, expectation satisfaction and extending network externalities to improve the continuous intention of using mobile game.

Online game business has emerged as the most lucrative entertainment Industry, with over 10 million players in South Korea. The popularity of online games can be attributed to the availability of broadband network and the presence of numerous PC Bangs and around the country, which have pushed online games Into the main-stream entertainment culture. The age distribution of online game players is expanding and a variety of new games are under development to target certain age groups. While the interactive entertainment market continues to expand, with many new online game publishers entering the market, relatively little is known about which factors influence online game players' behavioral intentions to play continuously in this area. It appears that in this extremely attractive and growing services segment, academics, as well as practitioners, would benefit from in vestigating the relationships among the players' loyalty, interactivity, the sense of presence and the impacts of several other key game-related constructs. Several types of interaction in on-line games and their relationship with the flow construct are investigated, and the resulting conceptual model is proposed. Based on data collected from online questionnaire survey, the validity of the simultaneous equation model has been tested and interesting conclusions have been developed concerning the relationships between the players' loyalty to the sense of presence, flow, satisfaction and interactions. Other interesting results concerning game development strategy are also provided.

In the clustering protocol, lifetime of the cluster members radically decrease because frequency interference between clusters make every cluster member consume a lot of energy to maintain or increase its transmission rate. In this paper, we analyze the frequency interference among the clusters with the game theory which deals with resource bargaining problems between players, and present a rational power allocation strategy. Both the cases that each cluster tries to selfishly occupy and cooperatively share the resource are analyzed in terms of non-cooperative and cooperative games. In simulation, we compare the cooperative game with non-cooperative game in terms of the node lifetime.

This study analyzes MMORPG in user's desire perspective and tried to find specific motivation factors. In research result, character has been separated in user character, another user character, boss monster and support character. And character's factor analysis yielded three factors: visual attraction, psychological propensity and competence. The result of the regression analysis about character's motivation factor show that it is significantly different that motivation level and motivation factors from each character. This finding implies that specific motivation factors can serve to make strategy for motivate user's game playing.
