> Thus making Linux irrelevant as target to game studios. For them DirectX and Win32 is what matters

I don't think so. I rather do believe that many game developers would actually love to give a more native approach for writing GNU/Linux games a try (to make this point more plausible: game developers are very used to game-console-native SDKs).

But what these game developers really demand is a very stable user-space API for everything that is necessary for writing games, which will work reliably on basically every GNU/Linux distribution, and will be supported for at least 20 years.
