For those who don't know, there's something called the Humble Bundle, which is a group of 4 or 5 really old and/or indie games. The catch is that, though you buy them, you can choose how much to pay -- $1 or $5,000 (or anything in between or above). You can also choose how much of your contribution goes where: multiple charities, developers for each of the games, and the Humble Bundle company itself. It's a really cool thing
This one has some REALLY awesome games! Psychonauts, Limbo, Amnesia: the dark descent, Sword and Sworcery, and something called Eff (only one I haven't heard of). Check it out!
