Hi, you may refer to this thread with the GM's answer to why VGN doesn't offer any other languages besides English.
"We are an international server with the main focus on English only.
It's not worth the time or effort to translate the game into other languages for only a small group of people that will actually make use of it. Items alone are over 60,000 lines of text, monsters are 40,000, quests 120,000 lines/sentences/paragraphs of text."
