Rules should be like the owners manual to a toaster or washing machine. Something your read once or twice and then stuff into a drawer somewhere and forget about because you know how to do it. This means simple rules. It doesn’t mean stupid rules. Rules can be quite simple and easy but yield complex scenarios and situations. My own rules for rules is what I call the 12/12. 12 pages single spaced, 12 point times roman bold all rules, diagrams, charts, illustrations, photos, and designer drivel must bit into the 12 plages, including cover art and masthead or you get out the red pen and start slashing.
Of the published rules, Moreschauser is the acme.
