title: iOS turn-based game server costs
body: <p>I'm planning to create a turn-based game for iOS (and later android). What would service would you recommend for me (like PubNub)?</p>
  
  <p>This might be a dummy question but is it completely free (for me) to publish a turn-based game in iOS using game center? So no server costs? If yes I guess this is the best way to create turn-based game for iOS only or how?</p>
