  194.                            <p class="info">This research explores the intersection of mobile gaming and behavioral economics, focusing on how in-game purchases influence player decision-making. The study analyzes common behavioral biases, such as the “anchoring effect” and “loss aversion,” that developers exploit to encourage spending. It provides insights into how these economic principles affect the design of monetization strategies and the ethical considerations involved in manipulating player behavior.</p>

  248.                            <p class="info">This paper presents an ethnographic study of online multiplayer mobile gaming communities, exploring how players interact, collaborate, and form social bonds through gameplay. The research draws on theories of social capital, community building, and identity formation to analyze the dynamics of virtual relationships in mobile gaming. The study examines how mobile games facilitate socialization across geographical and cultural boundaries, while also addressing challenges such as online toxicity, harassment, and the commodification of social interaction. The paper offers a sociological perspective on the role of mobile games in shaping contemporary online communities and social practices.</p>
