The study deepens into the transformative potential of mega-games as an innovative educational tool, offering profound and enriching learning experiences across diverse educational landscapes. Mega-games represent a fusion of various elements, including role-play, social interaction, simulations, rule-based systems, economic dynamics, political scenarios, and decision-making processes, all woven into an immersive narrative fabric. Through experiential learning, these games provide a unique platform for students to engage deeply with complex subject matter. This research centres on the application of mega-games within the context of sixth-semester students pursuing a degree in International Business at the Mexico State Campus of Tecnológico de Monterrey. Specifically, the study focuses on the simulation exercise titled 谈判 Tánpàn, which aims to immerse students in negotiation scenarios regarding the final price of a digital device manufactured in China. Drawing upon foundational principles outlined in Jesse Schell's book on game design, the exercise is meticulously designed to emulate real-world negotiation dynamics. The integration of game design principles, coupled with positive student feedback, underscores the efficacy of mega-games as potent educational instruments. Through rigorous analysis, the study unveils the profound impact of experiential learning on students' comprehension and application of negotiation techniques. By simulating authentic real-world scenarios, students are empowered to develop critical problem-solving acumen, hone their analytical thinking prowess, and refine their decision-making aptitude. Moreover, the immersive nature of mega-games fosters a dynamic learning environment that transcends traditional pedagogical approaches, fostering a holistic understanding of intricate subject matter. The success of the 谈判 Tánpàn simulation exercise serves as a testament to the potential of mega-games to revolutionize educational paradigms. It signals a burgeoning opportunity to expand the horizons of mega-games across various academic disciplines and participant cohorts. This study advocates for the widespread integration of mega-games as educational resources within Higher Education, championing their capacity to engender profound learning experiences and cultivate essential skills, heralding a new era of dynamic, immersive, and effective educational methodologies in diverse educational settings.
