Specifically, what do you think is the most important thing in a game?

Gameplay, Story, Graphics, and Sound are too broad and easy to claim as the most important part of a game.  So what do you as a gamer specifically think is the most important part?

For me it would be the pacing of a game.  In other words, the rate of speed that things happen and when they happen in the game.  Like right before a boss fight an intense storyline would lead up to it and give it more meaning instead of just fighting a boss and zooming right past a level, or getting items or abilities at an appropriate time to balance the game.
