How do you store your App's setting variables?

Just curious how people organize their application's global setting variables efficiently. When I refer to settings I mean data such as the size of a chunk in a tile engine, or the base movement speed of all characters in a game.

Currently I have a separate c# public static class named "Settings" and declare my const variables there for all my various scripts to access globally.

Is there a more efficient way?

 

Static class is a great way to organize your globals.
