The 400 So Far is an in-progress list of "The 400 Rules of Game Design". This week's CTCS 564 readings dealing primarily with rules, I thought these were quite interesting to look at, though they strictly speak to the designers of games and not the players. Practical advice such as: Concretize Ideas, Make Subgames, Add a Small Amount of Randomness to AI Calculations, Make the Game Fun for the Player, not the Designer or Computer, etc. - but also not so obvious, more esoteric ideas such as: Begin at the Middle, Creat AI in the Mind of the Player, Maintain Level of Abstraction, Use Real-World Formulas and Minimize Cheating with Simulations, etc.
