Dark Sector was cool but I'm not gonna play it again and it's worthless, this way I get something for it and I get to swap in my spare dirty PS3 case as well and keep Dark Sector's perfect case as my extra backup case. I ended up getting $6 which I applied to a PSN card.
Even though I told her I wanted to apply it to the PSN card she still had to make a gift card, put the $6 on it, and then redeem it. Kinda nuts!
