Rules of the game...the game itself...garb...weapons specs...shield specs...taking/calling shots...conduct...in depth of what you can and cant do, whats expected of you, your weapons etc. also the rules of how to play the game. Its not my call, but Id like to see something similar to the SCA rulebook, where everything is a little overly anal, but its well written as to whats expected of the player and the equipment.
