You may be wondering if your 30 days of game time (included with your purchase of the game) will be affected by the grace period. The answer is no. If you redeem your product registration code during the grace period, and add a valid payment method to your account, you will begin your billing cycle from then, and you will be entitled to 30 days of game time. If you redeem your product registration code before December 20th, your billing cycle will begin on December 20th at 12:01AM EST (the official launch date and time of the game).
