I got an email that inspired me to write about this next project: the most recent Humble Bundle computer game pack, the Humble Introversion Bundle, added another game, Dungeons of Dredmor, to its already impressive catalog.
If you haven't checked out this Humble Bundle or any of the previous incarnations, it's pretty straightforward. A number of games are provided (generally around 5-6) in a pay-what-you-want model. That's right, however much you think those particular games are worth, that's what you can pay. Often, as with this particular pack, games are added as time goes on, and some bonus games are included as well.
Your payment (if you give any) can be split between three parties - the developers of the games, a couple of charities (specifically the EFF and Child's Play), and Humble Bundle themselves for hosting purposes. You can allocate the funds between the three however you wish, so you can split it evenly, give it all to one group, or anything in between. Additionally, they are surprisingly open with the perceived value of the bundle, showing things like the average purchase amount and even breaking it down between operating systems, as well as the top contributors.
Besides the great content and reasonable pricing (really, you can pay nothing or support a charity, does it get any more reasonable than that?) Humble Bundle makes it easy to support them. The games are DRM-free, cross-platform in most cases, and you can checkout with PayPal, Amazon, or Google. They give you pretty much anything you could ask for to make it worth your time and money.
