Higurashi is a poor example for this. If there are 6 players left, 3 town and 3 mafia, and the day phase starts, usually the game is called. The reason for this is that the town can't achieve a lynch without one of the mafia joining them. If there is a double voter amongst the town, however, the game would not be called, because the town would have 4 votes. So you would end up with the game coming down to whether the town could lynch 2 futher times correctly without the double voter being killed. The exception to this is Mafia wincons that say "you win when you have parity", because they aren't factoring the total votes in to the resolution of the wincon (which is why I tend to use "Eliminate all threats").
