title: GameCenter turn based matchmaking
body: <p>I have a question about GameCenter's turn based functionality. The free version of the app will let users create a maximum of 3 matches at a time, and will block any attempt to create an auto-match or invite another player. My problem is the following, what if a player who has no limit of creating matches invites another player who has reached that limit, the game will take place, and i this is not what i want.</p>
  
  <p>Is there any property i can set to the player who has reached the limit of matches ? I know i can create the match and the disconnect the players if the conditions are not met, but this is also something i would really like to avoid.</p>
