Miiverse: Miiverse is a brand-new network communication system that lets gamers from around the world share experiences, discuss games and discover new content. Using their personalized Mii character, players enter Miiverse and see games, applications or entertainment content that either they have interacted with recently, expressed interest in learning more about or that their friends are using or discussing. From here they can challenge their friends to play together, ask a question about a difficult level or discover new elements of their favorite games they never knew existed. After a notable achievement or other share-worthy moment, players can pause their game or application and seamlessly post messages to the Miiverse community. TV Remote: The Wii U GamePad controller may also function as an infrared TV remote, whether users are watching TV or playing a game.
