Lol, the NA here (and generally in gaming industry) refers to North America, not North Atlantic. XD

Also, the primary (and only) difference is in region compatibility. Like nowadays (and even in older days), most games (the hard cases) comes in EU (Europe), NA (North Amrica) versions meaning a game of EU label won't run on a console (or device if you will) labelled as NA. That is it.
