Sairun: So the game is not available in German
I'd really like to buy the game , but only if I can play it in German.

On the GoG Page, by Searching of this game i found this.

Languages ​​:
Audio and Text: German , English , français

So isn´t that correct? Or what?
It's correct : ) There is a separate German installer for the game available in your account :)
