  194.                            <p class="info">This study explores the social and economic implications of microtransactions in mobile gaming, focusing on player behavior, spending patterns, and the potential for addiction. It also investigates the broader effects on the gaming industry, such as the shift in business models, the emergence of virtual economies, and the ethical concerns surrounding "pay-to-win" mechanics. The research offers policy recommendations to address these issues in a balanced manner.</p>

  221.                            <p class="info">This research investigates the potential of mobile games as tools for political engagement and civic education, focusing on how game mechanics can be used to teach democratic values, political participation, and social activism. The study compares gamified civic education games across different cultures and political systems, analyzing their effectiveness in fostering political literacy, voter participation, and civic responsibility. By applying frameworks from political science and education theory, the paper assesses the impact of mobile games on shaping young people's political beliefs and behaviors, while also examining the ethical implications of using games for political socialization.</p>
