Wii Karaoke U lets users sing along to the unedited versions of songs using their Mii avatar. The app features songs from a variety of genres, from pop to metal.
The game currently features a notice that informs users that songs not rated by ratings groups, but Nintendo told Eurogamer that it will go a step further. A new mature content warning will inform users before they download Wii Karaoke U that the game features potentially unsuitable content.
"It is however very important to us that all users of Wii Karaoke U by Joysound understand that some lyrics contained within songs may not be suitable for all audiences and as such we will immediately be implementing an additional message within the Nintendo eShop (prior to downloading the application and ticket purchase) as well as on the Wii Karaoke U by Joysound website pages," A Nintendo representative said. "
"In the near future this message will also be incorporated within the notification that is displayed as the Wii Karaoke U by Joysound application is launched."
