cant play s.e iv anymore

[Emperor's Child]

How can a game run that long without coming to some type of conclusion? Is this a one turn per week type of game, or have the players sorta agreed to "play nice" with eachother? In the games I've been in, once a guy gets pretty large, the game sorta goes to another phase where it resolves itself: either the big guy is killed by the smaller guys uniting, resulting in the smaller ones dividing up the spoils (and usually giving them the spur to go for broke themselves) or the big guy gets so powerful that nobody can stop em. How is it that a PBW game has gone on for so long?
