Purpose This study analyzed the topic of game review contents and how the characteristics of game reviews affect the reviews helpfulness. In addition, this study explore the content of game reviews according to the game's sales strategy such as early access strategy and releasing without early access. Design/methodology/approach We collected a list of 3,572 action genre games released in 2020. 58,336 online reviews were collected by random sampling 50 reviews in each games, and topic modeling was performed on those reviews. We dynamized the results of topic modeling and analyzed the effect on review helpfulness with multiple regression analysis. Findings The results of analysis indicate that the longer the review is or the shorter the time it is written, the more helpful the review is. In addition the topic with positive and negative review has a significant effect on the review helpfulness. As a result of exploratory analysis, games from early access had relatively fewer reviews of story-related topics than games that were released without early access. These findings can present direct guidelines for collecting specific opinions from customers in the game industry when releasing games.

The recent growth of smartphone users and high speed network has fueled the expansion of the market for mobile application. Among these applications with various purposes, smartphone games are the hottest contents on this market. Smartphone games are far different from former games due to their new input and output interface (e.g. touch sensors and gyro sensors).It is possible that the most resonable way to categorize these new smartphone games is comparisons of different objects, in this case, various smarphone games. But there exists no classification of the games neither for the use of the market nor the purpose of researches. Even though there are few classifications for games, those classifications have a major flaw that their criteria are derived from superficial features of games. In this paper, we propose a new method to categorize smartphone games through game mechanics of principal design components.

The purpose of this study is to identify what elements of VR games satisfy and continuous usage for the sustainable development of VR games. Specifically, an extended acceptance model was proposed with the addition of perceived costs, presences, satisfied variables to predict the acceptance and the intention of continued use of VR games. As a result, in general, it was found that the extended technology acceptance model with three external factors is more advantageous to explain the characteristics of VR game and its effect on users than the existing model. This study is suggested an integrated research model that considers the core characteristics of VR games and observe which factors lead to the persistent intention to contribute to the study about the VR game.

The purpose of our study was to figure out the generation gap between adolescents group and parents group in the sub-dimensions of perceptions on online games, such as harmfulness and benefits of online games, impacts and values of online games, parent-adolescent relationship with regard to online game activities, and government regulation of online games. To this end, we conducted online survey targeting middle or high school students and parents with children attending middle or high school regarding the perceptions on online games. As a result, we identified the similarities and differences between adolescents and parents generation in the sub-dimensions of perceptions on online games. Especially, we found significant differences between adolescents and parents generation in the perceptions on violence and sociality of online games. This result shows that the generation gap in these two factors may cause the conflict between parents and adolescents with regard to online game activities. Also, we ascertained the significant generation gap in the perception on parent-adolescent relationship with regard to online game activities. This result implies that parent-adolescent relationship in the developmental process of adolescents in real life was reflected in the perception on parent-adolescent relationship with regard to online game activities. Our contributions are in specifying the generation gap in the sub-dimensions of the perceptions on online games and in identifying the main causes of the conflict between parents group and adolescent group with regard to online game activities.

The purpose of this study is to investigate how young children's excessive immersion in smartphone games affects their prosocial and problematic behavior. To achieve the purpose, a qustionnaire survey was conducted with 147 children aged 3 to 5 going to two kindergartens and two child-care centers which were judged to have similar social and economic conditions, their mothers, and 16 teachers in charge of them. For data processing, SPSS 18.0 program was used to conduct frequency analysis, correlation analysis, and simple regression analysis. The study results were presented as follows. First, the more seriously the young children had excessive immersion in smartphone games, the more negatively their prosocial behavior was influenced. Secondly, the more severely the young children had excessive immersion in smartphone games, the more problematic behavior the young children had. This study is meaningful in the point that it analyzed the impact of their addiction in smartphone games on their prosocial and problematic behavior, and thereby helped to improve a plan of effectively using smartphones as educational media.

Background: Many studies have reported positive results of the various mirror training and virtual reality games in improving dynamic standing balance and posture adjustment in chronic stroke patients. However, no systematic study has been conducted to compare the effects of virtual reality games and the mirror balance training. Objects: The purpose of this study was to compare the effectiveness of Wii balance games and Mirror Self-Balancing Exercises in improving proprioception of knee joint and standing balance of people with chronic stroke. Methods: Twenty patients with chronic stroke volunteered for this study. The subjects were randomly divided into a Wii balance games group and a Mirror Self-Balancing Exercises group with 10 patients in each group. Each training was performed for 30 mins a day for 4 days. In addition to the balance training, 30 mins neuro-developmental-treatment based routine physical therapy was given to both groups. Proprioception was measured using two continuous passive motion devices, and static balance was measured using a Wii balance board. Dynamic balance assessment tools included the Berg Balance Scale, Dynamic Gait Index, and Timed Up-and-Go test. Results: All measured variables before and after the experimental results showed a significant improvement in both groups (p<.05). Only the improvement of the affected knee proprioception appeared to be significantly greater in the Wii balance game group (p<.05). However, other variables did not differ between the groups (p>.05). Conclusion: The findings suggest that both Wii balance games and Mirror Self-Balancing Exercises may be helpful for improving the proprioception of knee joint and the balance of patients with chronic stroke.

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.

The purpose of this research is to identify the determinants of loyalty in online games. This study developed a research model to analyze the factors explaining the loyalty level from gamers, employing social identification, flow, and positive anticipated emotion as major research variables, and collected 1308 survey responses from gamers. Within the context of arguing that the exploration of age range issues with respect to online games is important, this research also examines the age differences in path coefficients. To this end, the structural model was tested with the data from entire data sample (i.e., the age of 10s, 20s, and 30s pooled together) and each of the subsamples (i.e., teens taken separately, twenties taken separately, and thirties taken separately). Properties of the causal paths, including standardized path coefficients, the significance of difference, in the hypothesized model, are also presented, so that we can investigate the relative influences of different dominants, demonstrating how teens, twenties, and thirties differ in their decision-making processes regarding the flow, social identification and loyalty from online games.
