maybe some of you already know this organization: Humble Bundle.
They offer great "bundles" that allow people to get games at a really cheap price, the money you donate can go (in a percentage or 100%, depends on you) to charity.
Now they got a really interesting bundle for us "Managers": Tycoon-Simulator Bundle.
If you like the games, and you can afford 1, 5 or 10 dollars, that could really help people. In the meanwhile you'll have fun and "get something back from donating"!
Have a great day :)
