Not everyone is fluid in English.
Proving a point and stating it in one sentence is a talent!
Haha, you got me...

To all of you giving recommendations how to learn better English: thanks, but I'm already good enough. But not everyone is willing to do so or has the time to do so and a game should be entertaining or not.エ? If you don't properly understand most of what is written or said in a video game it's way less entertaining for people who are not very fluent in English.
And actually there is a localized version and there is no reason why it shouldn't be as good as possible.
