None of those things individually have any impact on the game. And none of them are likely to ever make it into a game by a company like Bethesda. The fact that you’re nitpicking these kinds of things, with no real basis, really makes you wonder the actual reasoning behind your post.
I’ve heard this a few times, but what does it ultimately mean? Doesn’t it mean that, if they desired, they could still operate and just not sell in Japan? Granted, obviously, if the dev is Japanese (I have no idea in this case and don’t feel like looking) then they’d have some issues, but for a western developer, it’d still be bad, losing all Japanese sales, but overall manageable.
