CRYENGINE Finally Lands On Linux
An anonymous reader writes: CRYENGINE, the video game engine from Crytek, will run natively on Linux starting from version 3.8.1. Other improvements include the ability to run on the Oculus Rift, support for OpenGL, 8-weight GPU vertex skinning, and improved POM self-shadowing. Here are the full release notes. They've also added Game Zero, a full blown example game that demonstrates how various features of the engine can work.
Star Citizen has modified the core Cryengine to add and tweak the features they need, I imagine rebasing on a new Cryengine version would be a ton of work. Possible, but I wouldn't expect it for release time.
You seem to be confused between games that Valve created versus games created by other companies that use Valve's distribution service named Steam. There's only a small handful of games distributed through Steam that were actually developed by Valve themselves; almost 30 if you include comercial mods and expansions.
It's not about Linux being this big juice target for developers, it's about making Linux ports a low enough hanging fruit for developers to target. Video game companies, like all businesses, are looking for a return on their investment. If the middleware you are using doesn't support Linux adding support is a huge cost with little pay off. But if all of the middleware you are using already works on Linux, there is a good chance the little bit of extra work you need to make your game Linux compatible can be a profitable endeavour. That is what this is about.
Linux has such a small share of the market it is silly to target that platform specifically, I mean Linux is only ~1.5% of the steam deployments. But if you can grab that 1.5% of extra sales for only a few weeks more work, why not?
