Guild Wars 2

I was just wondering, Did a mmo ever made a feature that you are able to type in the language of the race you playing as.

Like: when I type in English it translate it to the race language, so only the players from the same race are able to understand it because it show up for them in English but the other races sees it as the Language from the race your playing as.
(something in that way)

I think it would be fun to do that

Im not English so it sounds less fun as it should be

Yes, other MMOs have done that. Everquest is a prime example of that, with 25 languages (all fluent ones able to be selected by a drop down menu IIRC).

it was in EQ2, every race had their own language and if you did not have the quest complete to learn the language it was literal giberish to you in the chat window when they yelled at you or talked to you or w/e. Once you learned the language (it was a book collection quest back in the day IIRC) You could then speak it in the chat window and confound anyone who did not know it.

WoW have this.
By default your side(horde/alliance) understand, but if you play an elf for example, you can set language so that only other elves see what you write in English, everyone else see it in the Warcraft Elven language.

in GW2, the only language still alive (apparently) is new krytan, which is just english with different glyphs for letters.

i don’t think racial languages was ever an explored subject in GW lore.

Each race has a language but because they had to make sure they could all communicate from a lore pov they wrote in about a new language they call New Krytan that all of the races have since learnt and now naturally speak, similar to English in the real world.
