The folks at Humble Bundle have teamed up with Tim Schafer's Double Fine Productions to launch a Double Fine-themed bundle, where you can pay what you want and get DRM-free cross-platform copies of Costume Quest, Psychonauts, Stacking, and if you hit the right price, Brütal Legend and a preorder of Broken Age.
You can pay whatever you like for those first three games, though you'll have to pay more than the average (currently $7.03) to unlock Brütal Legend, and pay $35 to unlock a preorder for Broken Age. That second game is the product of Double Fine's record-busting Kickstarter drive, and it looks pretty keen. So, yes, this is basically a preorder shindig, but if you don't like preorders, you can skip Broken Age and still get some great Double Fine games for really cheap.
Oh, and if you drop $70, you'll get a t-shirt, too. In case you needed a t-shirt!
