The problem of translating the game is it's not gonna end updating any time soon. You have to update your file mostly manually each time something changes, gets added, revoked. And you have to keep translating.
The ones taking this up should be aware that without their constant participation the translation just gets outdated and partially incorrect/unplayable soon. They should order some tools to automatically do at least the chunk of updating job.
That's not to mention that the game is big and gets bigger.
Yeah, also some work is required to translate the interface items.
