Play games and support charity at the same time
Life is about the little pleasures. You know, things like ice cream on a hot summer day, cold beer at a ball game, and scoring big with the Humble Bundles. Yep, that sweet program that allows you to donate to charity (or developers) whatever amount you wish in exchange for some sweet games. The latest Humble Jumbo Bundle consists of Natural Selection 2, Sanctum 2, and Magicka with two packs of DLC, but as always, there's potentially more.
For those of you new to the Humble Bundle, the way it works is you set your own price and then decide how you want to split those funds between the developers, charity, and the Humble Bundle itself (paying for bandwidth and other associated costs). If you pay more than the average, you get a few extras.
As of this writing, the average is listed at $3.95. Beating that buys you the not only the games already mentioned (along with a few related soundtracks), but also Orcs Must Die! 2: Complete Pack, Garry's Mod, and Serious Sam 3: BFE, plus two more soundtracks. In addition, more games will be coming soon and you'll receive whichever ones they are by paying more than the average.
If any of that interests you, head over to the Humble Bundle website and go add to your games collection!
