Myslím, že za tím bude nějaký jeho osobní problém než problém s Linuxem:
C4 Engine customers needing Linux support can use C4 Engine 4.1 or older, including porting the old code to the new engine release, but Eric mentions they're forbidden from sharing that code with other teams. He says too in the future that they may support SteamOS but that they will not let the engine run on Linux in general.
