With reviews for The Legend of Zelda: Breath of the Wild, Nintendo has released the day one update, which will be adding online services and the Nintendo eShop to the Nintendo Switch. I've updated my system and the first thing that jumped out at me is the Friend Code is not dead in the year of our Lord 2017.
Once you've updated your Switch and linked your Nintendo Account, you can add friends! Your available options are to search for local Switch users, search for users you've recently played with, or search with a Friend Code. Friend Codes are 12-digital numbers, like they were on the Nintendo 3DS. There are no options to add users via a username or email address.
Unlike the 3DS Friend Code system, you don't have to trade codes. If you give a friend your Friend Code, they can send a Friend Request over. You'll receive a request with their chosen Username and Icon. You then have the option to Become Friends, Decline Request, or Block. If you Become Friends, the connection is done and they're on your Friend List.
There is a "Suggested Friends" section, that offers up users that you've linked up with through Miitomo or Super Mario Run, so you're not completely without hope.
If you are local, you have the choice to put the system in Local mode and choose the same symbol to connect. Unfortunately, I'm all alone out here and have no one to test it with yet. So, if your friends aren't local, get ready to break out the Friend Codes again!
The Nintendo eShop includes all of the currently release Nintendo Switch titles: The Legend of Zelda: Breath of the Wild, Super bomberman R, 1-2-Switch, Shovel Knight, Just Dance 2017, Fast RMX, Snipperclips, and I Am Setsuna. The "Coming Soon" section only lists Puyo Puyo Tetris and Mario Kart 8 Deluxe. Otherwise, you can purchase games, download demos, check any funds you have, redeem a download code, and add games to your Wish List.
