Serious games are well known for their application outside the games, but how they are developed is seldom explored. This study looks at the development process for an advergame for an outside client and what challenges and opportunities presented themselves when creating it. By looking at the context of development the study finds an understanding for what affected the development and how it affected it. The results show that the development context can have varying effects on development. Part of this is the motivations and background behind the project and goals of the company. The developers’ work can become dependent on the project company and work can be halted if the connection is not maintained. Further the study proposes guidelines based on the results that developers can use when working with interdisciplinary collaboration.
