The Settlers: Heritage of Kings - Scum in gog.
Without localizations:
- French,
- German
- Ukraine
- Russian
- etc.

Without official add-on and EVEN without last patch (also known as History Edition). Bravo! Better receive on torrents.

Why this? I often buy games, and if the preferred language isn't available, there are often language packs on the internet to download, official and fan made.
There's The Settlers II: 10th Anniversary as an example. A German game, but it's not available in German on GOG. ... It's Ubisofts fault why they don't supply the game in German for GOG.

I just download the translation in German, either by a link from the GOG forum, or by sites which provide translations.
