While online gamers actively participate in gaming teams, no study has yet explored whether gamers have sufficient teamwork knowledge and have accumulated sufficient team participation experience. These likely strengthen team commitment, but we do not know, indicating a research gap. Research filling th...

Online games are known for fulfilling computer users' various needs. However, little is known about whether real-world need satisfaction (not gaming satisfaction) motivates users to play online games. Grounded in self-affirmation theory (SAT), we develop a framework and formulate hypotheses to explain how aspects of real-world need satisfaction aff...

Purpose Avatars are known to be influential in gaming communication. However, little is known about how avatar attractiveness and customization impact online gamers’ flow, i.e., the experience of total concentration with intrinsic enjoyment and loyalty. Grounded in social identity and flow theories, the purpose of this paper is to construct a mode...

Online games can frustrate their gamers, but little was known about how such frustration impacts gamer loyalty. Because novice and experienced gamers may respond differently to frustration, this study investigates how gamers' frustration influences their loyalty and how this influence may differ between novice and experienced gamers. Because of the...

Online games have demonstrated dramatic growth both in revenue and user base, proving their value to electronic commerce managers. Online gamers are strongly motivated by their expectancy for growth, or anticipation of an increase in game level. However, the relevant literature has not yet explained how expectancy for growth impacts online gamer lo...
