title: UML class Diagram - Player Playing Game
body: <p>I am making a simple game with Users, where they can login to there account and can play games to try and beat there own high scores.  I have a 'Player Class' who then Chooses which game they want to play.  Is there a way to represent that a Player can be anonymous when playing the game?</p>
  
  <p>Would the correct way to do this be through Aggregation?</p>
