It has also been observed that intense grinding can actively damage the role-playing aspect of a game by making nonsense of the simulated world. A classic example of this occurred in "Star Wars Galaxies", where skills were improved by using them. It was, therefore, possible to see groups of three people, in which: one person was repeatedly deliberately falling over, taking a small amount of damage each time; another person was healing the first, increasing one's healing skill, and taking "stress" damage oneself; a third person was dancing for the other, relieving their "stress" damage and increasing their dancing skill. "Star Wars Galaxies" later revised the skill system with a sweeping overhaul called the New Game Experience (NGE). Several players left the game afterward, claiming that NGE made the game simplistic.
