title: does world size affect performance?
body: <p>Surprisingly I couldn't find any meaty info about this, so here I am. </p>
  
  <p>I understand that 1 unit in the editor = 1 meter, but does large worlds affect performance? I mean, they obviously do in sandbox games and other games packed with content. But what if it's mostly empty? My current project is a 2D Gravity Wars clone game with moving planets. Should I make it as small and condensed as possible, or is there room to scale things up? </p>
