Okay so I feel you don't understand what I am saying. There is a significant difference between early modern English (the John Adams clip I showed you) and modern English (everything basically after the 1800s). Queen's English, along with any dialect within England, American, Australia etc spoken today are all modern English. While you are correct that there are different dialects that are being used in GoT or the Witcher, it does not change the status that they are using a modern English. Of course, not everyone in ffxiv sounds like Aymeric. Limsa Lominsa is a good example, however, they are trying to mimic a style of 'pirate English' which I am not entirely sure ever existed.
Just fyi, this isn't something that I am just hearing, this is something that I actually actively study. This is from a historical stand point, not just this is my ears. And as for the Queen's English, it is an upper class form of English that is used in Downton Abbey and GoT. I never said that ffxiv or these shows used it excusively, so I am not sure why you are bringing this up. I used it because it is one of the most common English language styles that is used in your examples. Also the Queen's English is also known as Received Pronunciation which is known to be spoken by the upper class, or how you would put it social class/standing. So yes, those in Downton Abbey speak received pronunciation, for example. Also I've used actual documents written in Revolutionary era with words and phrases that are used in ffxiv in those videos. I can even link a video that goes on about tyranny and calamities put in such a way that you might think that the devs actually plagiarized.
Don't get me wrong, I find the translation fine. Adequate, even. But because of the large amounts they have to translate they should not have used early modern English. They should have used the English style in your examples. Once again, early modern English does not equal modern English. Queen's English or any dialect being used since the 1800s is modern English. The closer we get to today, the more comfortable the listeners will be. Also, because the type of documents I read daily, I am very comfortable with early modern English and I can sense it a mile away when people try to emulate it.
