This work is the result of comprehensive research into the quality of educational video games and its relationship with their design. We began our research by proposing a framework for the development of a specific educational game. This framework attaches great importance to the necessary balance between the ludic component of a video game and the educational content to be taught ((Padilla-Zea, 2009)). We have continued working on the process of enriching the evaluation of video games by incorporating the analysis of emotions that are produced in the player (González, 2011).
