I wasn't necessarily assuming it was translated. "Using kyoto as my base" could simply be a way of saying "it's huge." or "so big that I've lost track" or something along those lines. People have lots of different expressions like that around the world. You can't tell enough from a transcript. If he'd said it with a complete straight face, I'd maybe take it as literal. If he'd said it whilst laughing, I'd probably assume he was being hyperbolic.
I have no idea what you're going on about with the NES map. And there's nothing in that video you linked that says anything about specific sizes at all!
And what are you talking about Zidane being 400 feet tall? The world map in Final Fantasy games was purposefully out of scale. There is no world map screen in Zelda. It's all to scale! That's where the measurements for a game world actually come from, comparing it to the character's height.
