The language is inter alia German, but is the German only for the original versions or in addition for the Director's Cut (BS 1) / Remastered (BS 2) version?
The original versions are only available in English here on GOG.
Is it somehow possible to get the voice overs in german. I mean it shouldn't be that big of a problem, considering ScummVM is used to get the originals running. Perhaps it is possible for GOG to get the voice files and offer them as seperate download so the user can copy them over the english files?
Broken Sword is one of the few games where german voice actors are way better than their english equivalents (coming from someone who prefers original versions over localized stuff).
