This is a rule set in place to prevent or nullify complaints of people running up the score. It's simple, if you are to a point where the game is out of hand you simply DM your opponent saying "white flag" and you both begin to chew clock and call only running plays. An opponent does this when the game is either out of hand or they want to get the game over with. Basically if you don't want the score ran up then wave he flag, otherwise both of you play your type of game without holding back. This way there are no complaints of score being ran up bc the user has the ability to stop it from happening by conceding.

I like that.
