Hmm... Well, I do have an enormous backlog of games and it's not like I'd get to play it anytime soon. And even if it doesn't go lower during this sale, it will go on sale again eventually. So I'll wait for now.
The minimum level 8 to get these cards is absolutely fucking stupid, by the way. They're basically telling their customer base "hey, how would you like to pay real money, which we line our pockets with, for absolutely nothing in return?" You can't get to level 8 without crafting loads of badges, and you can't get all the cards for a badge without spending money (or trading, but obviously it's geared towards spending money). So in order to get this new meaningless badge, you have to pay enough money to get to level 8, then you have to pay more money to get all the cards. The thing that astounds me is that people actually do this.
Now, having the winning team get games from their wishlist is a good call. At least you're getting a prize there. Not just a little graphic that doesn't do anything. But after they've already nickel-and-dimed me for years with "European" prices for games, I'll be damned if I'm going to give them any more money just for a picture.
