You decide how much this pack of 7 awesome indie games is worth and how much of this money will go to the developers and charity. If you're feeling a bit more generous, you'll get the HB2 pack, another 5 great games, as a bonus. It's not just gaming, it's not just charity, it's supporting a much more honest business model.
Support indie game developers with the Humble Bundle, a collection of multi-platform DRM-free independently developed video games. All proceeds bypass middlemen and go directly to the developers and charities.
