When applied on a global scale these changes ripple through the entire world and cause
interwoven story lines to be created, to branch and to evolve into an ongoing
player created History; one where intelligent npcs behave realistically, initiating
independent action based on the social, political, religious and economic environment
in which they live, the environment that YOU help to create and shape with your Actions.

And because players have the ability to continually affect the state of the game,
...there's actually something going ON in OUR world!
