Just checked, and yes, both TW1 and 2 have separate online activations and region check. It doesn't rely on Steam for DRM, however. Although, you only get 3 activations and even changing a component in your PC will require a reactivation. "Buy the GOG version" is the moral of the story ;)

yes, once again. I was hoping IGS got a DRM Free version, too.

Get Games -75% off Borderlands 2 GotY - http://getgamesgo.com/product/borderlands-2-mac-goty

It says "mac", but it is a steam key so 1 key activates the Windows version also.

Note that it is the GotY edition, so not all DLC's are included. There are no complete versions yet, and it still gets the odd DLC now and then.

Note that the Desura BEEP is Linux-only, and the Steam BEEP is Windows-only.

Is it worth just for Dust? Not interested in the rest and read some mixed reviews about Dust. :I

A new Humble Indie Bundle already? It's been just one month since the release of the previous one. Still, for that price, Dust: An Elysian Tail looks mighty interesting. And the soundtrack of Giana Sisters is a very nice bonus.

Wow, the Swapper is in the $1 tier!

Yes I was surpised seeing that ... Well don't have any on those games so I think I will get this bundle.

Sweet Baby Jesus!!! '-'
Definitely one of the most epic bundles. My bets on unlocks: Rogue Legacy and Papers Please

I thought Dust was an excellent game. Not as long as I would have liked, but it was fun and looks beautiful. Dust is easily worth at least $1, but this is an awesome bundle all around.

Instabuy, I wanted Antichamber, Swapper and Guacamelee!

Antichamber doesn't show up as a Mac game in Steam...

Thanks, I'll wait for next HB Weekly and then I will decide. :)

Mac Antichamber is still live as a DRM free download from the Humble Library.

Unlike the other games, Antichamber has a publish date of today. If this were the first build at Humble there would be no date attached, therefore there was some last minute scrambling over a bug. It'll take a little while for the dev to get to know the full consequences of his fix, and then run everything through Steam QA.
