The only time "American" accents sound out of place is when they do not match the area. Having a Jarl and everyone in his court speak with some sort of accent only to have his children sound like some snotty west coast kids is very distracting.
Well, children often do speak differently than their parents. That's how accents evolve and change. But it is a bit jarring in that context.
It annoys me when I'm watching a movie/playing a game about ancient Greece or ancient Rome and everyone is speaking in British accents!
Come on, WTF. Even the American actors use fake British accents.
There is no excuse for giving Ancient Greeks English accents. Greek is still a language that hasn't changed all that drastically through its history. They should have Greek accents.
But seeing as no one still speaks Latin, it's kind of impossible to give Romans authentic accents. Why make them sound British? Americans view the accent as cultured and dignified, and generally view Romans similarly.
Has anyone else wondered what happens to these accents when the game(Skyrim) gets dubbed in other languages? In the French dub, do all the Nords speak French, but with a Scandanavian accent? or do they use various French accents or dialects instead?
