This thesis seeks a way to integrate popular psychosocial components required for believability to build a believable Non Player Characters (NPCs) model using the techniques of emergence. The believable NPCs model is scalable in terms of psychosocial models, customizable, flexible and data-driven. Comprehensive believable NPCs creation and management tools were developed to compose, generate, and maintain the system configuration data, as well as NPC profile data, using XML. Furthermore, a run-time prototype has been developed based on our proposed model to test its effectiveness. The prototype has also been evaluated for believable emergent behaviours in different social scenarios
