Here are two threads talking about in game languages :)

Welcome Kemikals and thank you, Rachael :)
As pointed out by Rachael, there are already several existing topics on language, we will, of course, release more information on this as development progresses but for the time being, I would encourage you to join in on those already active threads as I will need to go ahead and close this one down. Please use the search function prior to creating a new post as more often than not you will find that there is already a discussion going on about the same topic and we like to keep all discussions and information consolidated and easy to find for devs and members alike.
