The video game industry has become a dominant force in the global digital economy, attracting developers through unprecedented financial opportunities and a growing demand for engaging experiences. However, the push for rapid production and player retention often results in the widespread use of design strategies that may reinforce compulsive gaming behaviors. Adolescents—whose neurodevelopmental profiles heighten sensitivity to reward mechanisms—are particularly vulnerable, leading to increasing cases of Gaming Disorder (GD), now recognized as a global public health concern. Despite growing awareness, current development workflows lack integrated tools to assess and consider GD-related risks, and existing educational initiatives remain disconnected from industry practice. In response, this paper introduces GameDev MentorHub, an “on-the-job” Technology-Enhanced Learning (TEL) environment that embeds GD risk awareness directly into the video game development process. Built upon a multiperspective framework grounded in psychological science, the system aims to support developers through structured guidance, real-time risk evaluation, and context-aware learning—all within an “on-the-job” TEL system. By transforming the development process into a continuous learning experience, GameDev MentorHub aims to make responsible video game development both accessible and actionable in real-world industry settings.
