There are two big Humble Bundles happening right now as Double Fine has joined in as the Humble Weekly Sale. Also on Humblebundle.com right now is the Sid Meier Humble Bundle including Civilization III, IV and V plus other games of big Sid.
Double Fine joins in on the action by offering Psychonauts, Costume Quest and Stacking for a price of your own choosing. If you pay more than $6 you’ll get access to Brütal Legend and if you’re feeling extremely generous, you’ll get early access to Spacebase DF-9 if you pay more than $16.74.
