What worries me is that how will the reward system work out? What if players treat it more like a competition, like bug catching,What if this player kills another player just to put out a fire? You've got a 5-10 players fighting fires all at once, at least one of them is bloodthirsty for that fire truck mount and will kill players around them for the medals. And how would the players be rewarded? do you get a medal for each fire you put out? A medal for every 10 fires extinguished?
