Team Fortress 2 just had a nearly 1GB update, anything to do with the "event" going on today?
There are a bunch of games that got updated to support the trading card functionality, which recently went out of beta (no doubt in anticipation of this year's sale.)
I got 5 cards and sold them, which means I guess I'm not getting the Steam Summer Sale badge, but I don't particularly care for the gameification of the platform in the first place.
By the way, if any of you foolish people don't have Dark Souls yet, GET DARK SOULS. DO IT. DO IT NOW.
Or wait until it's $7.49 again, which it probably will be, but it's still a bargain at $14.99. I would just recommend that you have an Xbox 360 controller for it, as it is nigh unplayable with a keyboard/mouse combo. Don't even try, not once. It is an absolutely great game, though, just be prepared for something more challenging than your usual action RPG fare.
