Recently the game industry has been demonstrating much interest in the development of games that use more powerful Artificial Intelligence (AI) techniques. In this way, many games have been developed with more realistic graphics and character behavior. The game Black and White (B and W), developed by Lionhead Studios, is considered an important example of the use of AI techniques in games, and has resulted in a great success, disclosing a very interesting deliberative architecture for computational agents. Such architecture is based on the deliberative model called BDI (Belief, Desire and Intention). The present work aims to develop a study on the architecture used in game B&W, and also on the interaction of characters that use the techniques applied in this architecture. This interaction will use a protocol inspired on the communication language KQML (Knowledge Query and Manipulation Language).
