With the dizzying amount of indie game bundles lately, I've already started to observe that a lot of people are beginning to have difficulty keeping track of them all. What I'm aiming to do with this thread is to try to start a comprehensive index of what's been released in which bundle, and what sort of distribution's been used (DRM-free direct/torrent, Steam, Desura, etc.)

As expected, I aim to frequently update this thread with missing info, and with new bundles as they come along. Please let me know of, or post info for any bundles I haven't caught so I can update this main post (credit and +rep will be given, naturally). Unless indicated elsewhere, DLC (where applicable) is assumed to be Steam-only. Bonus bundles also include their respective soundtracks as well.

(EDIT: If there are any bundles I've missed or if there are any missing details, feel free to let me know.)

Well, I can always check HIB past and present time here: http://en.wikipedia.org/wiki/Humble_bundle Rest of bundles aren't such good so I'm not interested in them. :)

Man I actually own some games from a few of these that I freaking forgot about, lol.

To be fair you could go to Wikipedia (and much of the sale dates I got from that page) but I thought it'd be helpful to have that all in one convenient spot, so people could compare with other bundles.

Took me a while to notice the dates were MM/DD/YYYY...

Please add a warning/change them to YYYY/MM/DD.
Other than that, very useful information! :)

By games not socks (5(+1) games for $5)
Ran between: 11/06/24-11/07/03
I think they could all be downloaded DRM-free, though I'm not entirely sure.
Delve deeper (Steam/Desura)
Spring up harmony (desura)
Mactabilis (Desura)
Steel storm: Burning retribution (Steam/Desura)
Digitanks (Desura)

Bonus: Star-Twine (desura)

wow, grat recopilation

so, when do you think we are going to see a new HIB?

Nice work, especially with the non-Humble bundles.
If the amount of available bundles stays the same or increases, it would be nice to have a list of currently available bundles as well ;)
