title: Game engines: What are scene graphs?
body: <p>I've started reading into the material on Wikipedia, but I still feel like I don't really understand how a scene graph works and how it can provide benefits for a game.</p>
  
  <ul>
  <li>What is a scene graph in the game engine development context?</li>
  <li>Why would I want to implement one for my 2D game engine?</li>
  <li>Does the usage of a scene graph stand as an alternative to a classic entity system with a linear entity manager?</li>
  </ul>
