Virtual reality (VR) museum games offer engaging ways to interact with cultural heritage but often face challenges in maintaining user interest due to design issues or unmet expectations. This study employs a needs-driven approach using a combination of Kano and Analytic Hierarchy Process (AHP) models to identify and prioritize user requirements. Through literature reviews, expert consultations, and surveys, 24 key user requirements were established. Kano analysis classified these into 9 Must-be, 5 One-dimensional, 7 Attractive, and 3 Indifferent attributes, emphasizing the critical roles of realistic visual fidelity, interactive exploration, and narrative immersion. The subsequent AHP evaluation ranked interactive and gamified exploration highest (0.474), followed by narrative immersion and emotional connection (0.285), sensory and embodied immersion (0.157), and social collaboration (0.084). This research provides clear, data-driven guidance for improving VR museum game design, emphasizing interactive exploration and immersive storytelling to significantly enhance user engagement.
