There’s a lot of things that you can give Link to wear in Zelda: Breath Of The Wild. However, one thing that Link cannot wear is his pointy green hat. According to the game’s art director, Satoru Takizawa, it simply didn’t look that great.
Takizawa’s answer was more lengthy, explaining that “as the graphic fidelity has increased it becomes more difficult to make that hat look cool. As the game becomes more realistic it’s difficult to present it in a way that’s appealing. If you look at Twilight Princess, I really made the hat long, so it would flap in the wind and move around. But because of that people were like ‘What’s he got? What’s in that hat'”? Takizawa tried making Link’s hat diminutive in Skyward Sword, so it had less motion, but as Takizawa said, “we’re reaching our limits as to how we can make it look cool.”
