Even if Linux is not listed as a compatible OS in GOG, is compatible? I saw yesterday that Steam is selling it with full compatibility(Win, Mac, Linux, Steam Os). I would like to know this , because i'm looking forward to get a good computer and I would like to run it on linux, but I don't want to miss this game.

It will be supported soon.

Thanks!

Please make it happen i would love to have all 3 Witcher games on the same PC without dual boot.

We could start by making a petition with enough votes so Project CD-Red listens and starts bringing all their games to linux
