The goal is to keep our small community together.
However, if in addition to /trade /strategy /beginner we have /deutsch, and every player can use /leave deutsch command, I would not be against. All German community contributors would still stay on all English chats anyway.
Giving every single chat in the game it's own German version would be very problematic - German players would need to choose which languange they want to speak in game, and loss of hundreds players from English chats will hurt.
Also current state of the game motivates me to learn German -/-
