Video game software development consists of multiple disciplines with their own unique challenges. The key to successful game development lies in effective requirements engineering, which involves managing teams with diverse roles and transitioning from preproduction to production stages. Therefore, gamification project that build by game developer also present challenges during development. The primary objective of this research is to answer research questions that investigate the obstacles encountered by game developers with regard to gamification projects. The research analyzed both literature reviews and company game postmortem evaluations to gather data on what went wrong during development. The results of the literature review indicated that there are four categories of game development challenges and eleven subcategories of challenges. The criteria are game development challenges, internal challenges, technical challenges, and schedule challenges. This study examines challenges in game development by analyzing 69 "what went wrong"sections from six project postmortem reports. It identifies four significant obstacles: game development, internal issues, technical aspects, and time management. 44% of the challenges were attributed to game development, followed by internal obstacles (27.5%), technical problems (18.8%), and scheduling (8.8%). A deeper investigation revealed subcategories within these primary obstacles, with lack of documentation being the most prevalent (21.7%), followed by team management issues (17.4%) and technological issues (13%). These findings are consistent with those of prior research, indicating a pattern in the categories of obstacles encountered in game development, specifically gamification initiatives. By recognizing and addressing these obstacles, game developers can navigate the complexities of the development process with greater ease.
