@Teiman, I think you misunderstood my point. As much as I love Linux, (it basically powers the Internet) most of us use it headless.
Linux Desktop users belong to a rare breed that like to twink their systems, the mindset between power users who love to compile sources and tweek and build their OS and the apps and source level and the rest of us extremely different.
And I feel that this difference goes into the software installed. Again, How many SELF-RESPECTING Linux desktop will install a software that they have no access to the sources? It’s practically zero.
My feeling is that this extends into games. Practically nobody buys games for Linux, even when they exist. And that is the key point here. It’s less than 0.1% of sales. To put it into perspective, a game that sells 1,000,000 only made 1,000 units in Linux. That is abysmal for the necessary work required for launch and post sale support.
