In a world with internet shopping, "regions" should be irrelevant when it comes to purchasing and consuming...anything, honestly. Region locking should have stopped existing years ago.
Well they are and are not really.
Let's take Amazon.
Their US site will cover the us and their fr cover France/Europe (as far as shipping goes).
Some items can be shipped indiscriminately while other simply don't.
I still had to enter my payment info twice while the shipping info was still unique....and the handle/user login is also unique.
It's better to make what makes sense.
Digital content being locked to a region sort of make sense, since even if you're traveling you system can still connect to the region server.
For physical good? no reason at all.
Like at all, what will your customer do if he find himself on the other side of the Earth for an extended period?
You lose their money while they spend elsewhere because they can't use their stuffs anymore?
Nintendo is global and worked globally before.
There was a point in making console region locked since there was also the problem with tvs being different size and everything(NTSC/PAL/SECAM/50hz/60hz), as far as customers were concerned there might have been a safety issue or something to prevent it from being possible (not saying it was but that's explanation that doesn't look total BS at 1rst glance).
On handheld, the screen is always the same and there's no issue of power being any different, it just works.
The only reason it's not working is because they're being massive dicks.
