Link of The Legend of Zelda series has never been much of a talker, but that might be changing soon, as Nintendo is showing interest in knowing fan opinions of Link's personality.
There is a thread on Reddit dedicated to users who have received a survey about their experiences playing The Legend of Zelda: Breath of the Wild. The questions on the survey include ones that ask about the player's opinion on the personalities of both Link and Princess Zelda.
The Legend of Zelda: Breath of the Wild moved in a different direction with Princess Zelda, as she was presented as a far more vulnerable and unsure character than she has been in previous iterations of the series. The fact that Princess Zelda was now voiced by Patricia Summersett also changed how fans perceived her, as they could no longer imagine how Zelda's voice would sound in their own head.
It makes sense for Nintendo to be curious about opinions relating to the changes of Princess Zelda in Breath of the Wild, but it's odd that they would be equally as interested in the personality of Link.
The version of Link that appeared in Breath of the Wild was pretty much the same as he has been in other installments of the series. Link still lacks a voice outside of grunts and he isn't given much of a chance to develop a character in Breath of the Wild, as most of his conversation options are either meaningless or just fancier versions of "yes" and "no" responses.
The idea that Nintendo is curious about Breath of the Wild is also strange, seeing as it was released two years ago. It's possible that the rumored Breath of the Wild successor that uses the same engine is in development, and the survey is just a means of gauging player opinion while there is still time.
The next game in The Legend of Zelda series is a remake of Link's Awakening, which seems to be a faithful recreation of the original based on the footage we have seen so far, but this return to the 2D style of Zelda game seems to be a temporary measure to fill a slot on the 2019 schedule. A new 3D Zelda game will be coming at some point and the results of this survey may help to shape the kind of man that Link is when we return to Hyrule once more.
