elvis182: There are Polish subtitles and in-game menus available, but no Polish dubbing. All you need is to change subtitles language in .ini file from English to Polish.
Hemiq: Really? :) Can you make a screenshot with Polish language version (in videscreen (?) mode)?
Risen 3 has had Polish subtitles since it launched on GOG. When it first launched, there was no Polish language option during the game's installation, but you could use the Steam solution (yes, the Steam version also had issues with the lack of a Polish language version, and this mainly affected digital releases, as the physical edition had them) in the configdefault.ini file in the game files and run it as Notepad. After a while, the option appeared during the game's installation, but the GOG store still says that Polish isn't available :D. I'm attaching the attachments, and I know this is an old thread and probably outdated.
