On Thursday, November 22nd, we will begin pre-loading Baldur's Gate: Enhanced Edition for PC.
On that day, you will receive an email with instructions on how to access the Baldur's Gate: Enhanced Edition Installer to pre-load the game, or you can use the existing Beamdog client. In both instances you will need to log in with your Beamdog username and password. This information will also be available on the BaldursGate.com website, and here on the forums.
While the game data will be downloaded, the game will remain unplayable until final release next week.
