Abstract: The moral dilemma of violent computer games is that violent computer games are likely to cause players involved to practice violent behaviors in real life as well. According to Sicart's model， this dilemma is formed by the encounter between instrumental gameplay and violent content and behaviors that represent conflicts and its subsequent desensitization effects. It might be coped with from three aspects. First， the ethical game design of designers invites violent content in the form of game fiction to participate in the expression of ethical propositions with humanistic connotations in order to create conflicts between “procedural gradient of abstraction” and “semantic gradient of abstraction”， thus awakening players' ethical awareness. Second， the ethical gameplay means that players can actively use their ethical values to reflect on their game behaviors and manage the whole game system. Third， the regulatory authorities can manage by setting up rating systems， building online platforms， and improving career planning. Finally， the model is criticized and improved by adding the “technological gradient of abstraction”.
