http://www.humblebundle.com/ 6 pretty cool games for pc/mac/linux. You choose the price. Seriously. It's a charity thing. Check it out. If you pay more than the average (currently $5.07), you get 5 more games.
I have maybe 4 of the 5 games, and most of the games in the previous bundle. But this is good stuff. I love the idea, and hope we continue to see this in the future (though hopefully I won't already have 80% of the games in every bundle).
