John Carmack thinks the Steam Machine’s biggest problem is Linux

Speaking at Nvidia’s Montreal conference, Carmack noted that trying to force PC gaming over to Linux seems a bit crazy. Pushing developers to also develop a Linux port — or even crazier, to develop games with Linux as the main platform — is certainly asking a lot, and seems more like Valve is betting on its pedigree alone to pull developers over to aubergine color schemes and penguin logos. Though Carmack has been wrong about Valve in the past (and is fully aware of that), he’s not the only high-profile games developer that feels the Steam Machine’s future is murky.
