P.S. Expect lag..

EDIT: This came to my email:

This game requires an activation key and the Capsule client to play. You can pre-load the game via Capsule as soon as you have ordered it, however keys to activate the game will not be sent out until tomorrow. We will start distributing these keys from tomorrow afternoon (around 1600 GMT November 14th). Please ensure you run Capsule in administrator mode to avoid any compatibility issues.
