This paper aims at identifying the counsels that are necessary to achieve the Realization, Dissemination and Use of a Serious Game. In our opinion, these counsels are an additional facet for all Serious Game projects in order to target their ownership adoption and appropriate use (as intended by its designers) in a dedicated ecosystem (School, Hospital …). We propose to classify all these counsels in three main categories: R for Realization, D for Dissemination, and U for Use. By this way, we obtain a model named RDU. In a second step, we explain in detail the methodologies used to identify the fifteen counsels of the RDU model by using seven examples of Serious Games projects taken from a collection of 150.
