One giant massive hole in ME (in general) that really bugs me.

Completely understandable being that I feel the same way. It seems that some of us are so spoiled by how thoughtfully creative the developers were in terms of explaining ME's science and tech (all hail the codex) that the idea that any of this space magic not being fleshed out properly can really nag you. I enjoy sci-fi games over most others because the devs generally do a much better job at explaining how the fictional science behind their titles work. As compared to say fantasy titles that mostly utilize god tropes and mystical explanations that don't require that much thought. This does a hell of a lot when it comes to player immersion. To answer your question though I think there is a point where we as gamers just have to make do with what we're given. There really is no way to explain how a council race could immediately start communicating with a never before encountered species other than a "boss ass algorithm" delivering the goods in real time.

That would be very cool; I've no idea how much extra cost that kind of little touch entails -- but with that sort of thing you're guaranteed to conquer the hearts and capture the imaginations of quite a number of academic types.

In Assassin's Creed, 'translations' are taken care of by the 'Animus' device which reconstructs the entire life-story of an ancestor from the user's genetic info -- it's a bit too magical for my taste honestly -- but one of the little touches they've implemented is that there are occasional glitches in the simultaneous translation, so some words and phrases come out in the original language; and most of the environmental chatter is left in the original language. Though of course they don't have to invent any fictional languages for Assassin's Creed.

I haven't played Far Cry Primal, but I'm aware that they got real life historical linguists to come up with a very simplified version of the (reconstructed) Proto Indo-European language for characters in the game to speak. Here's an interview with them:



It sounds like the game contains a very small amount of talking; but that's enough to pique some people's interest.

Or we've gotten the Kett translation installed onto our system via the other Arks that arrived well ahead of us.  I expect this to be the in game explanation.  By coming late to the party we get to forgo all that awkward small talk and get straight to "surrender or burn" smack talk.   

I 'm just SO DAMN CURIOUS as to how aliens in the ME universe sound like. Not so much the languages themselves ,as much as the phonetics of them and the way they vocalize, the sounds etc.
The wouldn't need to make a whole language.Just some basic sentences ,expressions or words.

Anyway, does anyone know if it has been ever mentioned that the aliens in the ME universe have countries? Normally they should have different countries,regions therefore different dialects . For example a hint comes from Turians. You have the Roman sounding names that end is -us and then you have random names like Oraka.
