Unreal Tournament 3 was released for the PC nearly two years ago, and there was the promise of a Linux client and it was being worked on by Ryan Gordon, but to this day there is still no such client. Back in March it was said that it was still undergoing work, but there was no ETA for its completion...
Although from the day one I believed that I'll play this game on linux, but now I think that kind of statements are more like : "I'll tell community once a while that game is still under development so some poor noobs will still wait for linux client... *here put evil laugh* " :/
Should not be this difficult. Clearly something else is going on that they're not telling us. But whatever. Not quite dead yet is still better than six feet under. I'll still buy it if it comes out, but every day that passes diminishes how much I'm willing to pay for it.
We've moved on. The Linux community has already written it off as a failure to release, and due to broken promise after broken promise after vague/useless "update", will continue to treat it as such even in the off-chance an installer materializes.
Cut your losses and develop your next game with the lessons learned from the failure that was UT3/linux.
