They have a lot of other projects and of course they try to get the money for them with another HB. :D
Just have a look here:

Ugh, is Humble doing that again? I thought they tried it then stopped and did it a different way with the per game registrations to a Steam account or gift code. Looks like they're still trying to find their footing. I guess the safe play is to not instabuy things from them until one can confirm individual games can be gifted via keys or hyperlinks unless you actually do want every game in a given bundle for yourself. Very few bundles I buy do I want every single game, so wasting them on myself automatically wont fly for the most part unless there are several games I want really bad enough to justify the whole bundle cost for and write off the others.

Bundlestars is still my favourite bundle site overall though in terms of quantity of games and bundles I find personally interesting. I've gotten about 14 bundles from them to date and have 2 more I would like to get sometime soon - the "FPS Warriors 2" bundle, and "The Brutal Bundle" are the ones currently on my radar. All individual Steam keys so no guesswork on that. :)

The weekly is a repeat of the Double Fine Bundle from May 2013, except that BTA2 is now the Spacebase DF-9 early access instead of Broken Age.

Well, I'm usually not very fond of pessimistic predictions after some questionable first signs, but in this case I get a similar impression (and admittedly, these are hardly "first" signs). Their various projects are featured a lot... their projects in progress, that is. Apart from the first part of Broken Age, I don't recall seeing any finished material. And this repeat bundle is rather strange.

Looks really nice. I am a little disappointed that The Bridge is only available on Steam, but at $6 for that and 5 other games I do not own I will give this some thought.

amazing game!
a true masterpiece

I'm mainly interested the $6 tear rank because of Dear Esther DRM free version. I already have it on steam but haven't played it yet does anyone know how long it takes to beat? I'll try it over the weakened and if I really like it I'll go DRM free.

you can run through it in 50-60 min, but I spend a bit longer and you find different things. A couple of playthroughs is recommended.

OK thanks.

One doesn't really 'beat' or even 'play' Dear Esther. One trudges through it, looking at the scenery and trying to wring sense out of the increasingly bleak narration.

Thanks, I'll check it asap!

According to my Steam account it takes 81 minutes to finish this title. It's not really a game though, but rather a "living story" I believe they call it, where you walk around exploring while a narrated story is unfolded slowly. It's more of a form of artistic expression than anything.
