Winners in each category will be available for 30% off for the week after the awards are announced.
If you want to throw in your vote for the best games of the year, jump on to PSN today and make your picks. There are ten categories this year and voting in each one will earn you a background for your XMB.
Categories include the expected like Best PSN Game and Best PSN Exclusive as well as some categories you won't necessarily expect like Best 3D Game and Best PlayStation Classic.
No matter whether the games you chose win or not, you'll be in for a potentially very cool sale. Each category winner will be discounted by 30%, which increases to 50% for PlayStation Plus members. The unintentional consequence of which may be that people vote for games they don't own and haven't played in hopes of getting the discount.
