Chris Williams has written another great article based on his Heroic Adventure! role playing game. This one is about giving your creatures (non-player characters, monsters, animals, etc.) an artificial intelligence engine to make them appear lifelike during the game. He goes into an amazing level of detail regarding the various factors and traits you'll want to consider tracking. Check it out: http://www.informit.com/articles/article.asp?p=400031&rl=1. Thanks, Chris!
