Sony has once again opened up its "PSN Gamers Choice Awards," letting fan votes determine the most popular games of 2012. This year features ten categories consisting of three nominees each, and the winner in each category will go on sale next week.

Voting starts later today, and ends on February 25. Casting your ballot for any of the categories will get you a free XMB theme. The PlayStation Blog didn't detail just how much the winning games will be discounted, but last year the games were 30% off, or 50% for PlayStation Plus members. Check out the nominees list below.
