Imagine a system where both written and voice conversations are simultaneously translated...

I imagine that the conversations and history of both

[quote user="Arkham99"]Inserting different alien characters (with different voices/dialogue) into the same cutscenes is nothing new to this franchise[/quote]Think on how little the squad says during cut-scenes such as meeting Jack, compared to when it is
a set combination.

This isn't a technological restriction but rather a variable one. They have a short amount of dialogue because imagine having to script and voice (not to mention pay the actors) a full on cut-scene where the people bring with you are fully involved in that
conversation. You can't have the combination of Garrus and Liara saying the same things as EDI and Ash. Then you have to take into account the combination of Garrus and EDI, as well as Ash and Liara.

Each potential combination must be written and voiced to take into account who is there if you want cut-scenes like in Gears of War. I know you're not familiar with the series but Gears of War 3 is for me the best example of four player cinematic story-telling.

The xbox 360 had the option to choose the lenguage of the content. If you had choose english games where display in English. Plus other consoles have the option.

The problem changing the language of the system is that the entire console is in that language, imagine this, all text, titles, tiles and voice commands change to that language, in this case English. In my case I use voice commands all of the time in Spanish.

We need that option.

I honestly don't think there will be one. I can't imagine they'd have one on 3 platforms simultaneously.

The messaging system on Xbox One is imperfect and not exactly meant for many, or lengthy, conversations. You may want to try deleting some, clearing all the old, or simply using voice chat.
