In my case, there is a huge community of translators that do their job like professionals! Look at Divinity Original Sin, italian community translated the game and it was taken as official.
There are italian people that have already seen your language files, they can read but not edit them, cause of some kind of compression or something...
Please give us the possibility to work, it can be also unofficial translation, just like planescape torment... they do an impressive job and they realize our happiness!
