The random elements of the program must be completly separate from the scripts controlling computer players. It to obvious that the scripts controlling computer players are also controlling the random elements such as dice rolls and card selections. The compter players appear to be cheating all the time. The biggest flaw to Settlers of Catan is the boredom that comes from having no resources and doing nothing turn after turn. This is a huge waste of a players time. Entertaining the players should be your first concern with high quality game play, not a paperdoll of an avatar that you can dress up. We are adults not little kids.
