This is a really good deal. As in, financially good. Ethically good. Diversity good.
You get award-winning games and you give money to charity. Cross platform. DRM free. As much as you want. The money is divided any way you like.
The games are: World of Goo, Aquaria, Gish, Lugaru and Penumbra Overture.
I already owned World Of Goo and Gish through some deals on Steam but I put in $10 anyway with the full donation to charity just because it's nice idea.
