Following the success of the first 'Humble Indie Bundle
', a second collection has been launched, offering five different indie titles as a pay-what-you-want download to help raise money for both the developers and charitable organizations.
Braid, Cortex Command, Osmos, Revenge of the Titans
, and Machinarium
are all part of the pack, a collection of games with a combined retail value of $85.
However, visitors to the Humble Bundle site
are free to pay as much as they like for the collection, with the option of giving all proceeds to charity.
Potential buyers are able to allocate how much of their purchase price is divided between the game developers and charities the Electronic Frontier Foundation, and the Child's Play Charity.
At time of writing, 65,000 packs had been sold, with the average purchase price of $7.14 per download, for a total of almost $500,000.
The pack, which is DRM-free, is available to purchase for Windows, Mac or Linux operating systems.
The site offers detailed breakdown statistics that reveal, at time of writing, the average purchase price of the pack for Windows users is $5.94, for Mac users is $8.06 and, for Linux users is $13.52.
This indicates, perhaps, that proponents of open source software are also the most generous supporters of indie game developers -- although perhaps Linux users are also paying a premium because this is the debut of Braid
for the operating system.
The site points out that Cortex Command
and Revenge of the Titans
are still under active development, with buyers of the pack eligible for all future updates.
