Back at GDC in March, just before The Legend of Zelda: Breath of the Wild launched, Nintendo made an unprecedented revelation. It showed the tool it used to quickly prototype some of Breath of the Wild's gameplay mechanics and ideas. To make a long story short, it was practically a recreation of BotW's 3D world in the 8-bit 2D aesthetics of the original Zelda game. The developers should have expected that someone would be inspired by this. And, of course, it did happen. And so Breath of the NES was born.
