sentences:  From September 1, 2007 to January 1, 2008, varying implementations of this new system were used where players contributed points to a "pot" every turn and redistributed them according to number of territories held.This led to the birth of a strategy called "point-farming", an unpopular practice where the player in first place would drag the game out as long as possible to keep farming points out of the other players who were jockeying for place amongst each other.The update pushed out on January 2, 2008 was designed to do away with this practice—in a race that has basically been decided the player in first place will not be awarded extra points for extending the length of the game.
