One way I've seen IGOUGO moderated is in roleplaying games where a group of players roll for initiative in combat so that every combat sequence is different. You could wind up dead before even getting a chance to attack if you roll poorly enough. The original tin soldier napoleonic games were not unlike Warhammer. You could spend a fortune on miniatures just to reenact Waterloo, which had 118,000 men involved. In my very early youth in England, the old man living on the farm adjacent to ours was a "miniaturist" as he called himself and his parlor had a huge table set up with hundreds of individual soldiers. He used HG Wells rules. He would actually make his own figures. So, large extravagant war-games using hundreds of miniatures have been with us from the very beginning and is never going away.
