Only in english?

Do you know if the game is going to be translated to other languages?

That is a good question. Want to know to, if there are other Languages.

I think they’re gonna have pretty extensive support when it comes to Text language. Spoken audio is another story, though.

Yes.
Yesterday in Cologne there was the option to switch languages between German and English without restarting the game. I’m sure (but do not know) that several more languages will be available at launch.

Original AoE was available in several languages, and (correct me if I am wrong) in-game texts are the same in Definitive Edition, so it will have no sense not having the same languages availability. Is literally a copy/paste task.

Good news.
