YES. By the Omnissiah,
thank you. I was about to give up after I had traced the language setting to Mechanicus' Registry entry (the game stores config details there), and futilely tried changing it to English: The game just switches it back to whatever the OS default is.
To the devs, who likely aren't reading anyhow: Please understand that people may speak several languages, and the language their OS is set to may not be the language they want to game in. I need to have my OS set to German, since I have to provide support for clients that speak Germany
only. Having a game self-determine -without a sensible way of altering it! - the language it uses is poor craftmanship.
Please add an option in-game.
