So today’s big “OMGWTFNINTENDO!?!?!” news is that there are friend codes on the Switch, but don’t worry TOO much. Nintendo provided a statement to Polygon saying that more ways to add friends will be added later.
“Several methods can be used to add friends as quickly and easily as possible: · By linking Nintendo Switch to your Nintendo Account, your friends from Miitomo and Super Mario Run will appear as friend candidates so you can easily send them a friend request. Also, we are planning it so that friends from social networking services will be listed as candidates, too.
In the future, you will be able to send a friend request to friends associated with your NNID (Wii U/Miiverse) and Nintendo 3DS.
In some games you will be able to use an in-game interface to send friend requests.
You can send friend requests to those who have played with you recently.
You can establish a friend through local wireless communication.
You can also send a friend request by using a friend code.”
So there you go, for *now* it uses friend codes but there will be more ways to do it in the future.
How far in the future, I don’t know.
