I was hoping Payday would go on sale, but secretly I was hoping it wouldn't because I feel like I've already got too much to do. I've got a friend that will go in on a 4-pack with me if we can find a couple of people to split the remaining copies with.
I passed on the DX:HR DLC yesterday, the content didn't seem worth the price after getting all of the FNV DLC for a little bit more. Maybe xmas/new years will have a better deal.
I'd like to get the Civ V DLC, but I only paid $11.37 for the game. That makes it hard justifying $14.36 for the DLC (if you buy the bundle packs and the three remaining singles).
