Roleplaying is co-operative, not competitive. In order for a game to be good and for everyone to have fun, GM and players should work together and keep any rivalries in-character. In most games, the story should be about the player characters, and if it's not necessarily about them, players must at least feel part of an important story, as people who are responsible for advancing, shaping, changing, or even derailing the story. Fun should be the number one priority.
