This video does an alright job at explaining why the Localization is so different

That's because the other two localization teams felt using the more 1:1 was more suitable for their target audiences. Meanwhile the English team chose a style that made the localization be aimed at North America.

Given averages in scholastic achievement across all English Speakers, I still believe it's a pain they chose EME (Early Modern English) as the dialect for the man.

I'll warrant that it's done purely for flavour, not because this archaic form is more suitable to English Speakers - fluent or native - let alone those with lesser ESL skills.

Whilst I have little issue reading EME, time and time again the complaints on these fora, and in other places, show a significant number of native speakers do have issues with EME.

Taking this idea further, head off into the Localization (sic) forum and look at some of the common complaints about things like "corse" being a mistake. That single word, and how much confusion it causes, is enough to prove these choices were not made with 'more suitability for the target audience' as a reason.

It's not like the JP team doesn't also do this. Look at the Namazu, they used a different dialect than what they use for the majority of the game.

I don't have an isssssue with the beast-tribe-ones having unusal speech mannerisms. yes, yes. They are an adjunct to the story.
