This study provides a foundational analysis of how live-service game models and transmedia strategies are reshaping the contemporary video game industry, with a particular focus on Games as a Service (GaaS), player engagement, and franchise longevity. As gaming continues to outpace film and television as the world’s most lucrative entertainment sector, publishers face growing pressure to sustain player communities, balance monetization with satisfaction, and extend intellectual property beyond the game itself. Part 1 examines the historical evolution of GaaS and game adaptations, situating SEGA’s legacy within today’s competitive landscape. Drawing on existing literature, industry reports, and market context, this section frames the central research questions and methodological approach that guide the study. By establishing the strategic challenges and opportunities facing live-service games and transmedia franchises, Part 1 lays the conceptual groundwork for the data-driven analysis and recommendations presented in Part 2.
