Attention!
This is not the current Double Fine Bundle that includes all their games.
This is the Humble Double Fine Bundle (including Psychonauts, Stacking, and Costume Quest Steam Keys), that never got it's own page so this old ID was always used when giveaways were made. You can find easy the old threads discussing that matter.
If anyone has any objections we can discuss it with a mod.
This steam ID does not exist anymore so you'll not get any disparity between games won and games activated.
