title: Can Game Center integrate with non-game iOS application
body: <p>I am working on an education application but I want to implement a leader board and achievement feature to it. So I come up with Game Center.</p>
  
  <p>My question is, this application is now in the education category and I don't want to move it to Game category. Will it be rejected in the application review because I integrate Game Center with a non-game application?</p>
