Most Intriguing Game "Worlds"

From a nostalgic reflection on a mushroom kingdom to an overdone collection of wordvomit to flesh out gameplay elements. This is my ongoing list of Game Worlds that interest me. You know the ones...the ones that keep you on wikipedia or giant bomb till 3 AM for no good reason.

Note: I'm not referring to large engrossing worlds like Fallout or Morrowind...more the elements of a story that make you want to dig deeper.
