My biggest wish for this game and further installments of the franchise is to give more languages available for gamers! In this way you can reach more potential people who don't know English, German or Italian and these are not their first language.
You could just try to implement a few new languages, especially Polish, as the biggest country in Eastern Europe with one the biggest game development market or Japanese. Also, with this addition you could gain much better image, because when for example Polish community got to know that State of Decay 2 won't be available at least with Polish subtitles they wasn't so happy.
Please, really think about it!
