The Humongous Flash Bundle is on now, with a bunch of Humongous Entertainment games for cheap, with a portion to go to charity. Best of all, if you pay $20 or more, you can get all of the games that have been released on Steam so far (that's 1/5 of the usual price). You'll also get DRM-free versions for Windows, but if you run a different operating system, rest assured that most of the games run on ScummVM, so if you run the Windows versions of the game through ScummVM on the platform of your choice, you'll still be getting the same experience.
