BioWare has announced plans to allow Early Game Access to fans who pre-order Star Wars: The Old Republic. The early access will grant players the ability to create and play your character up to five days ahead of The Old Republic's December 20th launch.
Notice how I said "up to five days", meaning BioWare has plans to stagger the Early Game Access over the five days to "ensure a quality experience for players at launch."
Early Game Access will be granted according to when your pre-order code is redeemed at the Code Redemption Center. "Staggering access aids server stability and a gradual increase in player population through the game," BioWare said.
