Have no excuse for not producing Linux versions of their games.
Because it is a lot less work porting code written to run on BSD to run on Linux, than from Windows to Linux.
Gaming on BSD?
Yes lots of us do it. But it is not obvious. I have devices with Orbis OS, Cell OS on them, both are BSD based and both sold very well. Both have lots of really good games.
So if you want a game on Linux and the publishers are not interested, if there is a Playstation version remind them that the Playstation OSes are forms of Unix, just like Linux.
