LARP Backstory A LARP session is only as good as the character relationships and plot points which drive it.  Coming up with new situations with enough things going on to hook the players and drive interaction forward is a challenging endeavor and can lead to flat game play if not done well.   At least one player who organizes LARPs intends to use a game of Universalis to help develop the character map and plot points for an individual run; and also to advance the story arc between runs.
