I have yet to see a good implementation of more than one language on a server.
Unless you can make it that you checkmark a radio button to select your language on autopatcher and from there on the game is all in your language automatically (only other lang you would see is in player chat), there is always that taste of alienation when pple see other langs other than their own in npc and other game dialogs.
Even if you made it as easy as selecting your language in autopatch, it would still require server owners to provide the text input for that other language and I don't see it being realistic. I find it amazing that Koreans and Chinese have such a problem with English when for most other nationalities English is pretty well sort of a second language, even officially in some of them.
LOL my lang is missing up there in voting but I don't complain and my countrymen wouldn't complain either if they played (too bad mir is unknown among them). Since computer gaming started out, they all got command of English at least sufficient for playing games.
