I installed Gothic 1 by Lutris. In installation, I selected Polish language, but game is in English.
Another thing is game resolution is larger than screen resolution, but only in menu - in game resolution fits screen resolution.
I try to edit installation script, but there’s no url of gog installer (exe file).
It asks for the setup file so it does not download anything.
You need to download the Polish version from GOG manually first and then run the Lutris installer. It will then ask you for the setup file and set everything up accordingly. As you downloaded the Polish version, the game will be in Polish.
Mkay… I tried the import as you described and it’s not working at all for me.
However downloading the game from GOG manually (in the desired language other than English) and using the install script on the site works without problems. Maybe give it a try.
