Although one of the fundamental goals of Al is to understand and develop intelligent systems that have all the capabilities of humans, there is little active research directly pursuing this goal. We propose that Al for interactive computer games is an emerging application area in which this goal of human-level Al can successfully be pursued. Interactive computer games have increasingly complex and realistic worlds and increasingly complex and intelligent computer-controlled characters. In this article, we further motivate our proposal of using interactive computer games for Al research, review previous research on Al and games, and present the different game genres and the roles that human-level Al could play within these genres. We then describe the research issues and Al techniques that are relevant to each of these roles. Our conclusion is that interactive computer games provide a rich environment for incremental research on human-level AI.
