With the popularity of online games, the overuse of these games has raised concerns. The literature has mainly conceptualized players' psychosocial characteristics as risk factors for game addiction. However, many studies have confirmed that game structural characteristics play a more important role in players' experience. Similarly, this research investigates how interactive affordances of World of Warcraft motivate players to play the game excessively. We have used two qualitative methods of Think-aloud protocol and in-depth interviews with World of Warcraft players. We recruited 35 World of Warcraft players from Singapore Nanyang Technological University in May 2021. Twenty of them participated in the in-depth interview and 15 of them participated in Think-aloud protocol sessions. We found that strong social ties in persistent groups encourage excessive gaming and causes sleep deficits, bad eating habit and ignoring real-life duties. Intra-group competition for outperformance encourages excessive gaming because players receive powerful items if they spend more time on gaming. Rewards and contingent tasks that are designed in games to encourage playing the game with time encourage players to play the game excessively. Finally, after explaining about gaps in knowledge, we discuss how our findings contribute to the literature. Implications for future research and insights to game addicts are provided
