Zelda producer Eji Aonuma has told 4Gamer that The Legend of Zelda: The Wind Waker HD for Wii U only took the developers six months to develop. However, Aonuma said that despite this, development was quite difficult as the team had to take into account the differences in hardware. Additionally Aonuma said that the game utilises a technique known as toon shading, which gives the game a very animated look which was hard to achieve.
4Gamer: I see. My impression is that there is a good balance between feeling of the original and a fresh feeling at the same time.
Aonuma: Yes. I thought it would be a waste to for this to simply be a test of the hardware. After that, I was told by staff, that this would not take too much time to develop. It takes a long time to develop a brand new game, so I thought it would be a shame to not have a Zelda game on the Wii U for a while. So I felt like it would be best to deliver something that can be done quickly and began work on the HD version.
4Gamer: Ah I see.
Aonuma: With the original release of Wind Waker, the first half of the game was well received, the later portion on the other hand, needed to be re-evaluated. That was my first time in control of the direction of the game and designing a game from scratch, there were some portions that I wanted to expand upon. If a remake were to happen, I believed I could work on some of those portions.
4Gamer: Does that mean the development time was not so long?
Aonuma: It took about 6 months. Development was still difficult. You had to consider the difference in hardware at the time. Additionally there is a technique known as toon shading, which gives the game a very animated look. At that time, the technique was established, but had not be used before by our staff, everyone had to do everything by hand.
