Nintendo is making some big changes to how it operates and especially how it views mobile software. While its not technically a game, its first app, Miitomo, is still noteworthy because it's the first of many planned apps with its partner DeNa.
As its customary in Japan, you can now pre-register for the app via this website. In doing so, you'll be the first to know when the app launches or when Nintendo wants to do some tests.
Miitomo works with the new, unified Nintendo Account that also just opened. You can register for a shiny new account here. With it, you'll be able to earn platinum coins that you'll then be spend on a store. This account system is also a bridge between Nintendo's systems and mobile devices.
All in all, this is a small but important step towards Nintendo's first game on mobile. We should have more info about it this year but we already know it will feature an iconic character from Nintendo's treasured IPs.
We'll post about it as soon as we have more info. Until then, look forward to Miitomo launching in March.
