One of the important balances a GM must strike at his table is the difference between a game that follows conventions and expectations, and one that is very spontaneous. As a narrative experience, tabletop roleplaying requires a particular mindset and flexibility, even when it focuses more on numbers than on people. An important element of this is to figure out what players will enjoy, and offer them an appropriate experience; games are not fun by default, they must be made fun through the events within them.
