It just seems odd for id to always release their game engines as open source, but not support an open source platform. A fair amount of the work done on their released game code is developed on Linux with Windows/Mac support added later, not the other way around. Hopefully Valve will lobby id and get Linux support for Rage/Doom 4. I also heard the editor or DLC might have been coming this April for Rage, but "when its done" is driving me nuts.
As far as I understand it's not that id is opposed to a Linux port, so lobbying will probably not help a lot. If someone at id was willing to spend their spare time on porting the game, they would probably release it inofficially. I think that both Valve and id have similar policies with regard to Linux except that Valve currently has developers that care about Linux.
Well it seems you need to be stupid to buy the game on steam then

Who cares?
That's NOT quite correct- so you are at least misinformed on parts of this. Quake3:Arena was an official build for Linux, supported by Loki games. When there was a slight 3-week delay in getting it into our hands, people bought the Windows SKU and "patched" it to run on Linux. The reason we didn't see any more from Id officially was that the Linux SKU only sold 200 total units because of the aforementioned conduct- we COULDN'T WAIT. Before you comment, I was a beta tester and ISV (as in outside driver developer- at the time, one of the maintainers for Utah-GLX...) for Loki games at the time.
As for Rage... If TTimo's no longer working for them, it may be a bit...since, like you said, most of the versions've been unofficial, as much to ensure it ran right on multiple platforms. The reasoning they had was that if they expended an extra 10% of effort on things and could make a Linux version that worked you would be sure that the code was pretty robust, running on 3 different OS platforms and running well.
