This paper proposes a conceptual model for non-player characters for use in a serious game application. The game is aimed for teacher training with a focus on training of social skills related to conflict handling. Conflict handling is difficult to emulate in a realistic way and appears not frequent enough in the practical training part of teacher education to enable sufficient training. Also, training in a real world situation may be ethically less sound. To develop a serious game for conflict handling training, we need to create non-player characters that can emulate conflicts in a realistic way. For this, we need to extend current models with social and emotional aspects. We present previously developed meta-models that enable us to propose such a model and combine these and recent game research to a Model Social Game Agent.
