While I really wish we had OrbusVR in other languages as much as you do, that was posted some years ago:
In a nutshell, translating the game content would take more reprogramming than expected - not to mention we’d need volunteers again, considering not all volunteers from the first post are active players anymore.
EDIT: another thing to consider is that if we had multi languages the way the game runs now, we’d have even smaller communities of players in their own language.
