I am afraid that everything official is: ``We do not support anything different than WinXP, Vista and Win7.''
1. This is a new
Game. So the original Sourcecode and the original devolopers are available .
2. This means that GOG.com has no need to fiddle with the codebase for them selves.
3. It's legally ok to add the Linux port as a free goody with no warranty to the Windows game.
So there are no big issues for GOG.com to add the Linux port as a free goodie, right?
