1: Write your rules such that you don't need examples of play.
2: Edit your damn rules...a lot...
3: Then include examples of play because, no matter how broad your circle of friends and testers (definitely not the same thing), somebody won't think about a rule quite the way you do.

Oh, and, by the way, please make sure that your example actually comports with the rules. "Fighting Sail", the new Osprey age of sail miniatures rules failed in this rather dramatically, although the author stepped up and owned it
