Applying inexpensive AI techniques to computer games

Groo (Generic Robot, Object-Oriented) and tt14m (Trash-Talking 14-year-old Moron) are two systems that use simple and computationally inexpensive artificial intelligence mechanisms to produce engaging character behavior for computer games, while remaining within the performance constraints of modern game development. Groo engages in intelligent tactical behavior in a first-person-shooter death-match game using a fairly simple and static behavior network, while tt14m uses simple text processing to attempt engagement in the social aspects of the game "Counter-Strike".
