I think it is essential to have language support in these kind of games.
Steam has a lot of games with language supporting, and also in Walking Dead series and Wolf Among us has the language support with plenty of languages.

I do not love better steam, do not misunderstand me.
But I love to got the same quality for my money!

So dear GOG please work on the language support especially in adventure games, especially on the popular ones:
(deutsch for first, french, spanish etc...)

Kind Regards,
