  194.                            <p class="info">This study explores the role of user-generated content (UGC) in mobile games, focusing on how player-created game elements, such as levels, skins, and mods, contribute to game longevity and community engagement. The research examines how allowing players to create and share content within a game environment enhances player investment, creativity, and social interaction. Drawing on community-building theories and participatory culture, the paper investigates the challenges and benefits of incorporating UGC features into mobile games, including the technical, social, and legal considerations. The study also evaluates the potential for UGC to drive game evolution and extend the lifespan of mobile games by continually introducing fresh content.</p>

  221.                            <p class="info">This study examines the growing trend of fitness-related mobile games, which use game mechanics to motivate players to engage in physical activities. It evaluates the effectiveness of these games in promoting healthier behaviors and increasing physical activity levels. The paper also investigates the psychological factors behind players’ motivation to exercise through games and explores the future potential of fitness gamification in public health campaigns.</p>

  248.                            <p class="info">This paper investigates the role of user-generated content (UGC) in mobile gaming, focusing on how players contribute to game design, content creation, and community-driven innovation. By employing theories of participatory design and collaborative creation, the study examines how game developers empower users to create, modify, and share game content such as levels, skins, and in-game items. The research also evaluates the social dynamics and intellectual property challenges associated with UGC, proposing a model for balancing creative freedom with fair compensation and legal protection in the mobile gaming industry.</p>
