/**
  * World creation
  *
  * Here is where a round itself is actually begun and setup, lots of important config changes happen here
  * * db connection setup
  * * config loaded from files
  * * loads admins
  * * Sets up the dynamic menu system
  * * and most importantly, calls initialize on the master subsystem, starting the game loop that causes the rest of the game to begin processing and setting up
  *
  * Note this happens after the Master subsystem is created (as that is a global datum), this means all the subsystems exist,
  * but they have not been Initialized at this point, only their New proc has run
  *
  * Nothing happens until something moves. ~Albert Einstein
