In recent years, considerable interest has been devoted to the application of games for educational purposes due to their potential to improve learning process and learning outcomes. Such trend can be explained by several reasons, e.g., games increase enjoyment, involvement and motivation, as well as they induce emotions. It is considered that playing games is more emotional than rational process and research shows that emotions are fundamental to learning. They influence perception, attention, decision making, motivation, as well as acquisition and retrieval of knowledge. Learners usually differ regarding their interests, preferences, personality and all these aspects can be considered to provide adaptation. However, differences of individual learners are seldom considered in educational games and emotions as an adaptation source are used even rarely. The main aim of this paper is to introduce a multi-level adaptation approach for personalized educational games to improve their adaptability.
