What is online multiplayer?
You can play games with other players from around the world on Wii U and Nintendo 3DS family systems! Many titles can be played over the internet, either with friends or random players. To play with friends, they must first be registered on the system's friend list.
Certain titles, such as Mario Kart 8 on Wii U, even allow two people to play online together using the same system, so you can keep a watchful eye over your child's play session while sharing the fun!
Some titles also support communication between players, such as the ability to exchange preset messages, text chat or voice chat.
As with other online functionality, it's possible to restrict access to online multiplayer using Parental Controls.
