This seems to come up regularly when a question is raised relating to the balance of power between the GM and players. What invariably happens is that people all have different interpretations of this, often based on how a particular game's rules are phrased.
This often leads to long discussions in comments, which I always understood was not the ideal way of doing things.
Are we handling these questions the best way? Is there a 'correct' answer that can be given with this type of issue?
