Along with viewing the eShop on both the GamePad and the TV screen, players can view and rate games, and read comments related to the game from Miiverse. The eShop can download content while a Wii U software is running, but it’s unclear as of this point whether this applies to all downloadable content and games on the Wii U eShop or just small DLC packs.
