Battlefield 4 Creative Director Extols Virtues of Linux as a Gaming Platform
We're seeing it primarily from Valve with its upcoming SteamOS and Steam Machine boxes, though also from developers. Lars Gustavsson, the Creative Director of DICE who has worked on nearly every Battlefield game since the first prototype, believes Linux is just a single "killer" game away from blasting into the mainstream market.

"We strongly want to get into Linux for a reason," Gustavsson told Polygon. "It took halo for the first Xbox to kick off and go crazy. Usually, it takes one killer app or game and then people are more than willing. It is not hard to get your hands on Linux, for example, it only takes one game that motivates you to go there."
Suffice to say, Gustavsson is super excited about what Valve is doing with Linux. Whether or not Steam Machines will turn the tide remains to be seen, but if nothing else, a little competition doesn't hurt. Gustavsson likens the situation now to the VHS era.
"You know, was the VHS tape better than BetaMax? VHS won," Gustavvson says. "So it does not always go in the right direction but overall I think it is healthy with competition."
