This master’s thesis presents some of the challenges concerning Greenland’s future development in terms of large scale projects, and how these can affect the local community. It will then be examined how a serious game can be used to simulate a large-scale project scenario and how such a game can be used to inform the player about possible consequences and problems, as well as collect data regarding choices and priorities for future studies. Subsequently, a description of the development of a “proof-of-concept” prototype of a scenario-based serious game will be presented as well as the testing and test results from test participants. Despite several issues concerning the testing, the results indicate that a scenario-based serious game could be suitably used for citizen involvement in regard to information, feedback retrieval and debate generation, provided a suitable amount of resources are utilized for the development and testing of the game.
