This paper examines the values and risks of Serious Game Jams from the perspectives of participants and considers the significance of participation based on these findings. The identified values include: experiencing collaborative creation within a team, acquiring game development skills, learning about the social issues that serve as the theme of the jam, gaining achievements, and building a network. On the other hand, the risks include: unhealthy activities and physical fatigue, the breakdown of self-esteem and pride, conflicts within the team, and stress and pressure. Considering these aspects, the significance of participation can be summarized as follows: personal growth through learning and practice, achievement acquisition and career development, and social contribution through self-expression.
