The increasing complexity of video game development highlights the need of design and evaluation methods for enhancing quality and reducing time and cost. In this context, Model-Driven Development approaches seem to be very promising since a video game can be obtained by transforming platform-independent models into platform-specific models that can be in turn transformed into code. Although this approach is started to being used for video game development, there is a need for usability evaluation methods specifically tailored to this type of development process. In this paper, we present a usability inspection method that can be used along all the stages of the model-driven video game development. The method relies on a Usability Model that is aligned with the ISO/IEC 25010 (SQuaRE) standard and decomposes usability into measurable attributes and metrics specific for the video game domain.
