Gamification design is considered as the predictor of collaborative storytelling websites' success. Although aforementioned studies have mentioned a broad range of factors that may influence gamification, they neither depicted the actual design features nor relative attractiveness among them. This study aims to identify attractive gamification features for collaborative storytelling websites. We first constructed a hierarchical system structure of gamification design of collaborative storytelling websites and conducted a focus group interview with eighteen frequent users to identify 35gamification features. After that, this study determined the relative attractiveness of these gamification features by administrating an online survey to 6333 collaborative storytelling websites users. The results indicated that the top 10 most attractive gamification features could account for more than 50% of attractiveness among these 35 gamification features. The feature of unpredictable time pressure is important to website users, yet not revealed in previous relevant studies. Implications of the findings were discussed.

Purpose -Sociability is considered to be important to the success of educational MMORPGs. The purpose of this study was to access the relative weights of these sociability factors which the authors garnered from the literature on educational MMORPGs. Design/methodology/approach -The authors used fuzzy-AHP approach to access the relative weights of these sociability factors they garnered from the literature on educational MMORPGs. To do this, a questionnaire using a pair-wise comparison data input format was administered to 242 school teachers to gather assessments for the factors. Findings -The authors found five most important factors affecting sociability -cooperation, teambased reward, discussion of strategy, reputation, and social navigation. Originality/value -Although prior studies have identified various factors that facilitate sociability in educational MMORPGs, the relative importance of these factors has not been determined. The results can not only be used to help educational MMORPG developers focus on the most important sociability factors and propose specific guidelines for designing educational MMORPGs, but can also identify the best design strategy for promoting sociability of educational MMORPGs.

The need for teamwork has grown significantly in today's organizations. Especially for online game communities, teamwork is an important means of online game players' engagement. This study aims to investigate the impacts of trust on players' teamwork with affective commitment and normative commitment as mediators. Furthermore, this research includes team experience as a moderator to compare the difference between different player groups. A model was proposed and tested on 296 online game players' data using structural equation modeling. Findings revealed that team experience moderated the relationship between trust and teamwork. The results indicated that trust promotes more teamwork only for players with high experience through affective commitment than those who with low experience. Implications of the findings are discussed.

Because of the evolution of community supported collaborative learning (CSCL), the online community has become a necessary aspect of most companies and organizations. Previous research has indicated that employee community commitment is the fundamental function of an organization, which has proven to affect a person's teamwork performance. However, research focused on how the online community-supported collaborative virtual environment, such as enterprise social network (e.g., Yammer) or virtual working space (e.g., SUN's Wonderland) might alter community commitment to affect a person's teamwork self-efficacy is scant. The authors examine the mediating role of community commitment with emotional social support as an independent variable and teamwork performance as an output variable. World of Warcraft (WOW), a dynamic high-fidelity virtual environment that can support hundreds to thousands of people collaborating together, serves as the research platform in this study.The authors conducted hierarchical regression analysis to explore the causal-effect relationship among the factors of emotional social support, community commitment, and teamwork self-efficacy. In total, 558 current company employees selected from WOW participated in an online survey. The authors' findings showed that individual commitment positively influences teamwork self-efficacy. To increase individual commitment, the online community can provide a high level of emotional social support to members.
