Yeah, seriously. Every time someone says that Nintendo doesn't have an account system, you come in saying that in fact they do. Going by your logic, Nintendo had an account as far back as Wii goes (Wii shop account), your games were just tied to the serial number of the console. What's the difference between all your games being tied to a serial number or a NNID? The only thing I can think of is that you can have multiple accounts on a single Wii U but I'm not sure if they even allow the transfer of individual accounts. And yes, they could also do the transfer over the phone back then, they were just very reluctant to do so because screw the costumers, we got our money.Holy fucking fuck. Seriously?
I'll still humor your BS:
It is an account system that has all your digital purchases registered to it. This is fact. This what many have been crying for for years. Now the goalposts have been moved to "oh but I want to move my account around at will!" which is a completely understandable thing when a system breaks or whatever and the current call CS solution is far from ideal. For the fucking record: nobody is claiming the latter part is perfect, painless and anything to celebrate in and of itself! Could this please be recognized for fucks sake?
So, now. Deleting your account is not a self-explanatory thing? Really? Are you seriously trying to sell me on that? It even tells you that you lose access to your shit.
You didn't say anything about switching countries but switching countries is exactly how you switch eShops. Which you can still do, you just can't log into your NNID. And you can still use the eShop without an NNID since creation of an NNID is not mandatory on the 3DS.
No, because Nintendo doesn't exist in a vacuum, even if their actions make you wonder if they think they do. MS and Sony don't allow you to close your account; you can only delete your profile. It's not a stretch to say that someone coming of XBL and PSN would expect the eShop to work the same.
Read again what I wrote: ''So a NNID functions the same way as a 3DS' eShop account, except you can't switch between eShops from different countries anymore.''
You also imply that you can still access different eShops.
''Thus you can't download demos from other countries stores since there's only one NNID per 3DS.''
You can't download shit from other eShops once you register a NNID on a 3DS.
