Nintendo has announced that gamers and fans will be able to pre-register for Miitomo, the company's first mobile app built for the iOS and Android platforms.

According to the press release, pre-registration will get fans some goodies.

Starting Feb. 17, people will be able to pre-register for Miitomo by signing up for the new Nintendo Account service using their existing email, social media accounts or current Nintendo Network IDs. People who pre-register will be among the first to be notified about the availability of Miitomo when it launches in March. Nintendo will offer a special Miitomo bonus to anyone who signs up for a Nintendo Account between Feb. 17 and launch.

What's Miitomo? I'm still not entirely sure. Nintendo routinely offers vague descriptors about social interaction through the game and its use of Miis, but that's about it. Miitomo has no screenshots or trailers to speak of, and it really hasn't been shown off to press.

Here's how they described the game today.

Miitomo is a social experience that uses Nintendo's Mii characters, which first debuted on the Wii console, to engage friends in a lighthearted and welcoming environment. Users can spark fun conversations and learn more about each other by answering questions such as "What song has been stuck in your head lately?", "Do you believe in aliens?", or even "If you saw a nose hair sticking out of your friend's nose, what would you do?" Users can also easily take and share photos featuring their Mii with the Miifoto feature.

The release also brings news of the rewards program Nintendo is launching to replace Club Nintendo. It's called My Nintendo, and it will release alongside Miitomo in March. Nintendo did not get too specific about My Nintendo, stating that it "aims to become much more than a traditional rewards program."

It is a more comprehensive service that rewards users for interacting with Nintendo products and services in a variety of ways. Miitomo users with a Nintendo Account will be able to take advantage of My Nintendo to enhance their experience.

This will likely be entirely different from responding to surveys for coins and using them to earn free goodies.

We'll have more on both Miimoto and My Nintendo as it comes.
