AI (Artificial intelligence) in serious games

Here at Fachgebiet Technische Informatik, we particularly engage in the field of AI-technologies of Serious Gaming. These following questions are of interest to us:

• What kind of AI technologies are particularly suitable for leaning games? 
• What kind of AI technologies are not suitable for learning games?
• How can the expert knowledge be implemented easily and effectively in learning games?
• How must the expert knowledge be formulated for the learning games?

Concerning this, there is a project with integration of an expert system which provide the expert knowledge for a serious game.
