title: What is the advantage of using OpenFeint or Game Center?
body: <p>my company is developing an iOS and Android platform game which needs to track high scores and achievements. We use Unity 3D.</p>
  
  <p>Is there a special advantage to using OpenFeint or Game Center for scoreboards, other than that they strip away the need for dedicated game web server / database? I read somewhere that the best practice is to design your own Facebook scoreboard server similar to Doodle Jump or Bejeweled Blitz, because it increases user engagement, but we're really not sure which option is the best for us.</p>
  
  <p>Thanks!</p>
