Interesting article by Jeff of Wolfire games about supporting Macs and Linux. Includes a very nice cake.
Wolfire developed the third-person action title Lugaru for Linux; the blog entry mentions that the Linux port generated additional interest in the game, and that Linux users made up 5% of their sales (which is pretty much unchanged from the Quake III sales over 10 years ago if I recall correctly). Wolfire’s next game is a sequel to Lugaru, Overgrowth. You can find more info about it on Facebook.
