The Humble Indie Bundle is 5 games, DRM-free, available for Linux, Mac, or Windows. You pay what you want and decide how much goes to charity. I bought it, but I haven't had time to download any of the games yet. I'm looking forward to playing Braid in LInux.

I got an email today that the original bundle has been added to my download page. If you beat the average price, it's included. I'd been wanting to try World of Goo.
