What a shame.. I make a point of buying only Linux native games. But they should understand this.. it wont stop me playing the game. If they would like to turn a profit from me, then Linux port it.
If you're referring to piracy for spite, let me just add that if I have to install windows and boot into it to play an idsoftware game, then I WON'T pay for that experience, as I have consecutively done in the past.
I have to have it though. Screw Epic Games and their middleware-bloated UT3, they're dead, but Rage looks phenomenal: johnc is probably right when he assumes we'll all swallow a windows install for a few weeks.
On a related subject, the recently Wolfenstein game apparently runs quite well out of the box in wine. Any game like this that has an opengl renderer (or is an otherwise "wine-friendly" game) will receive my monies. Interestingly enough, these games oftentimes have lineage back to one of quake engine iterations -- Call of Duty 1-2+4, All Source Games, etc.
I expect this thread to balloon in size, and I assume many other GNU/Linux user's will have taken to Quake Live as I have (it's excellent, and deathmatch is back baby), so I really would argue for the existence of a substantial and growing market of linux gamers. This market contains a higher _percentage_ of informed and loyal customers.
id software has a strong community dedicated to it (regardless of OS), and the company is able to leverage that very effectively. Why can't id, or any company, just come out and say: "It's gonna take us $10,000 + snacks to have Timothee Basset or Icculus produce a port. We've got about one year left of crunch time, give us the 60 bucks early on paypal, and if it all pans out, you'll get the game when it's released with an assured linux port, or a refund." I know I'm naive about the figures and costs involved, but I do believe that faithful linux gamers like myself would actually be very inclined to support this kind of "pseuedo public-financing". Add on to that the probability that the engine technology will most likely be free software in 5-10 years, it almost seems like we're donating to some kind of public works/cultural program.
TFA, which is genuine, makes me sad.
