A reader pointed out that the FAQ for the Amazon Lumberyard [Official Site] game engine no longer lists Linux support, so I reached out to Amazon to see what's going on.

Here's what it said originally:

Q. What device platforms does Lumberyard support?

Lumberyard currently supports PC, Xbox One, and PlayStation 4. Mobile support for iOS and Android devices is coming soon, along with additional support for Mac and Linux. […]

And now:

Q. What device platforms does Lumberyard support?

Lumberyard currently supports PC, Xbox One, PlayStation 4, iOS (iPhone 5S+ and iOS 7.0+), and Android (Nexus 5 and equivalents with support for OpenGL 3.0+). Lumberyard also supports dedicated servers on Windows and Linux. Additional support for MacOS is coming soon. […]

I reached out to Amazon about this, since another AAA game engine supporting Linux would have been a really great thing. It seems they haven't seen enough demand for it:

Hi Liam, Lumberyard does support Linux for dedicated servers (which it didn't at the time the FAQ was written). Linux support for servers was a very important request from many of our customers. As for a Linux-based editor / runtime support, we're keeping a close eye on what our customers are asking for. Right now, there's much more demand for a MacOS editor, which we're working on. If we get more demand for Linux for the editor and runtime, we'll definitely add it to our roadmap. Thank you for reaching out to us and letting us know that you're interested in Linux support, I've let the team know.

I know there's a few people excited about Star Citizen, which switched over to the Lumberyard game engine, so hopefully this isn't too big a roadblock for them. Well, that's if Star Citizen is ever finished.

The silver lining here, is that not many games are actually using Lumberyard, so it's not a major issue. The most popular game engines like Unity and Unreal Engine do support Linux. I would actually be rather surprised if many developers did use the Lumberyard engine, since Unreal and Unity are so deeply entrenched in the minds of game developers.
