Talkirc (atys)
... the UI NEEDS BUILT IN TRANSLATION FOR ALL BASED ON THE UI SELECTED LANGUAGE, THAT WAY I CAN WRITE IN ENGLISH AND A FRENCH PLAYER CAN READ WHAT I SAID AT THE SAME TIME ON HIS OWN CLIENT. (but saddly our game just doesn't have the funds for that, so we're all out of luck.)....
Find some game where this kind of things is implemented .... Ah, this doesn't exist, maybe ? There must be a good reason for that.
You definitely can't demand something from the actual Ryzom that no other game editor, with obviously more potential, don't ever tried to do. As far as i know, international servers just use english as language and don't care about anything else. client may be translated, but there is absolutely nothing that translate discussions from player of a specific language to language of another player.
Ryzom has already automatically translated emotes, and a few translated interaction texts (check your key settings) .... but you can't have a roleplay session with this.
