You should head over over to Wolfire games (http://www.wolfire.com/humble) and pick up some of the best indie games made in the last year or so. These are real games that can be had off of Steam as well, the would probably cost you over $100 seperately. Known as the humble bundle, this has gotten some pretty great press.
I paid $20 and skewed it to the charities that can optionally be supported (its a 50/50 split otherwise.)
Pay what you want, get some good games and feel good about supporting the indie developer community and charities. It is a win all the way around!
Only about a day left as I post it, so if you are thinking about it pay now and thank yourself later 🙂
