The game will be available only in English, French and German. The game is language-dependent: even if we use many icons on the cards, text is pretty common. This makes it harder to provide a complete translation of it, and we do not plan to add extra languages at this point.
It's not in the works for this campaign, as this game has been designed for a multiplayer experience. It would need too much tweaking for this first release, without compromising our production calendar.
But in the future, who knows ? :)
