Day 100 - Lens 84: The Lens of the World
The world of your game is a thing that exists apart. Your game is a doorway to this magic place that exists only in the imagination of your players. To ensure your world has power and integrity, ask yourself these questions:

How is my world better than the real world?
The players have the autonomy to change the world, and a clear pah to try to do it. In most narrative ways the game world is dystopian and not at all better than the real world.

Can there be multiple gateways to my world? 
How do they differ? 
How do they support each other?
Right now there might be two gateways, the gameplay itself and the fiction found in the game documents. I want to expand that fiction and perhaps add art around the game and perhaps even music. All of these would be in the form of artifacts from the game world. The game is very different than the fiction of the world, however the fiction and the art of the world are similar. All of the aspects of world building are describing the same place and they all are structured to support the action of playing the game.

Is my world centered on a single story, or could many stories happen there?
Right now the world is centered on one story, but it's an interesting world and the possibility of more is at the very least implied.
