Conventional LARP wisdom declares that a veteran player (IE Cool Kid™) is worth a dozen newbies because a veteran can do the roleplay legwork to attract or retain a dozen newbies. As a consequence we allow storytellers to devote a staggering amount of time to insular, in-group, fan-service plot to keep a select few players interested. But if resources are devoted to veterans at the expense of newbies, is that veteran still valuable, or are they worthless?
Trick question: if you have to assign numerical value to a player, the game is already over, and so is your LARP. Go home and abuse your buddies with a good old fashioned tabletop game of Paranoia.
