Rules Lawyers can come in many different flavors, ranging from obnoxious, to helpful, to just plain dumb. Every gaming group seems to have one - that one player who memorized the entire rulebook cover-to-cover and is more interested in the rules than in the actual game being played with them.
Some rules rarely come up, after all, and it would be insane to memorize them all, particularly for something as complex as a Tabletop Game. In most games (and Real Life, too), players can often get by without knowing every single rule. Alleged quote from a historical wargamer disputing an opponent's movement Explanation Four inches is 101.6 millimetres, so the player was disputing 1.6mm/0.06 inches of movement distance.
