The games in this second Humble Indie Bundle include Braid, Cortex Command, Mechanarium, Osmos, and Revenge of the Titans. The game titles aren't too amazing, but they're all natively available for Linux, Windows, and Mac OS X.
What is that supposed to mean, not too amazing? Just because it's not from Phoronix favorite "Linux company" Valve?
I never played Braid, but almost everyone gives it high remarks, and now it's available for Linux! Also Revenge of the Titans looks fun.
