This is a great idea for Windows, Macintosh, and Linux users, and while some losers may choose to pay these guys NOTHING - in fact, doing what amounts to piracy for what is truly a generous act - I'm sure you'll all agree with me that buying/donating money for this amazing bundle of games is not only the right thing to do, but a sound investment for the future of this type of thing (a bundle of high-end DRM free and cross-compatible games, plus source). Here's the info from the Website, so head there now and get your own bundle (http://www.wolfire.com/humble):
"The Humble Indie Bundle is a unique kind of bundle that we are trying out.
Pay what you want. If you bought these five games separately, it would cost around $80 but we're letting you set the price!
All of the games work great on Mac, Windows, and Linux. We didn't want to leave anyone out.
There is no middle-man. You can rest assured that 100% of your purchase goes directly to the developers and non-profits as you specify (minus the merchant fees).
We don't use DRM. When you buy these games, they are yours. Feel free to play them without an internet connection, back them up, and install them on all of your Macs and PCs freely.
Your contribution supports the amazing Child's Play charity and Electronic Frontier Foundation. By default, the amount is split equally between the seven participants (including Child's Play and EFF), but you can tweak the split any way you'd like.
And now, thanks to a humble donation from Amanita Design: all contributors are given a free copy of Samorost 2!"
