Nintendo amazes me: as an organization they make incredible games yet are terrible at everything else.
Don't forget, they are very new to mobile. Things that may be obvious to mobile devs are overlooked by a large company used to a captive console audience. Nintendo doesn't move quickly but they are very adaptable in the long run.
I refuse to buy it purely for this fact. Not because I want to pirate it, but because I do most of my mobile gaming while on a plane. And I'm not paying for in-flight WiFi just for Mario.
It looks like it's either console devs doing this, or Nintendo wrote some strict console-like requirements. Like login before you see anything and "you have to interact after the loading screen" silliness.
