We are almost done with the Game's localization, and we will soon be able to test all the languages.
Guild of Ascension will be available in : English / French / Spanish / Portuguese / German / Japanese / Chinese (simplified and traditional).
So I'm sure you're gonna find the languages your are the most comfortable with to enjoy the game :D
The localization is a long process, and we will need to test it a lot to make sure everything works as indented, but we are very happy to offer the game in all those languages :)
