American city ship not the united states and its in a different universe means that any accent goes. Also, they could even be mexican if its american. It would be xenophobic to exclude any one. It`s obvious. 

Actual european history requires european accents. Therefore this is logic. 

Yu also used the term "british accent" which isnt a thing and now you come out swining as if your an expert. 

Also please refrain  from being abrasive.

A couple of things.

One. A game based in New York is not going to be populated with Englishmen simply because "York is an English city, therefore New York is also an English city" ;)

However the ship did have an American flag, so I would expect most accents will be American.

Two. It helps with the whole immersive nature of a game if you are able to see yourself in the protagonists, maybe friends in other characters. Likelihood there is that your native accent will help that, so despite the ship being American I hope there are British accents (which do exist, encompassing a range of accents on the British isles) in the EU release, Aussie for the oceania release. Unfortunately for those regions I think the powers that be will cut corners and just pinch the American voice acting> So I hope they pick good voice actors!

And my point was that Xenoblade X takes place in an American setting (American city) and by your logic should have American voice-actors, hence contradicting your claim of xenophobia.

...Of course it would be an issue. American's have American accents. They absolutely need to have American accents. Maybe the Nopon and other races will have other accents, but it would be plain stupid and honestly enraging for them to make the New LA natives speak with an incorrect accent.

Actually I never used the term British accent. Use ctrl + f please.  I used the terms received pronunciation and English accent, which are indeed things. It's quite  obvious you don't know what you're talking about. Medieval people in England spoke middle english, which has nothing to do with the language spoken today in England (and the U.S) other than being its ancestor. It is a vastly different language than both its decendents are to one another. Some Americans (whom many are of English decent) speak a dialect of English that is more archaic in some ways than RP (Received Pronunciation.) So it is silly to say that RP is closer to Middle English than Standard American. Then your final argument is a silly location-based one. Well I think New-Los Angeles is definitely an American city. It has the American flag on it and all.

edit: By the way, I was matching your abrasiveness, by your declaration of xenophobia while mantaining hyper-nationalism.

In a fictional city named after an American city with a giant America flag and giant letters spelling "United States" on the shell of that city, no they can't.

Quote trees please guys, remember to keep them below three.

It's like a forest in here!

...Context clues. You should have been able to "ruin it" for yourself ages ago. This has been common knowledge for years.

I swear you can smell them from a mile away.

Haha I was going to say this. Like Eddie Murphy in The Nutty Professor.
