The Legend of Zelda: The Wind Waker HD was released last week in Japan to a lukewarm reception.
According to Siliconera, the title only sold 30,000 units in its first week.
Zelda was also outsold by much smaller gaming franchises, such as Armored Core and Warriors Orochi.
This is just another title in a long line of Wii U releases that have flopped. Though Nintendo has been putting out quality titles, (Wind Waker HD has a 90 on Metacritic) the public hasn't been interested in purchasing a Wii U or its library. In fact the PlayStation Vita has sold more units than the Wii U in Japan.
The Legend of Zelda: Wind Waker HD was released digitally in North America on September 20th. The physical copy will come out in stores October 4th. You can read more about Nintendo and the Wii U's struggle here.
