Humble Bundles are charity-driven ways to buy video games; usually popular independent ones. This time, software biggie THQ is getting in on the act:

You choose how much to give. It can be as low as one dollar to unlock the entire game bundle, except Saints Row. For unlocking that, you simply need to donate more than the current average (right now it says $5.64). All proceeds go to your choice of the Child's Play Charity, the American Red Cross, and/or to THQ.
If you like Real Time Strategies, there's none better than Company of Heroes and it's two expansion packs.
