title: TypeError: Cannot create a consistent method resolution order (MRO)
body: <p>This is the code which I plan to use for my game, but it complains about an MRO error:</p>
  
  <pre><code>class Player:
      pass
  
  class Enemy(Player):
      pass
  
  class GameObject(Player, Enemy):
      pass
  
  g = GameObject()
  </code></pre>
