I am actually quite impressed with Link's Awakening's sales. If I'm correct it is currently the best selling stand-alone, 2D Zelda game! I think it's safe to say that Breath of the Wild has expanded the Zelda fanbase a great deal.
EDIT: The original Legend of Zelda on the NES still holds the crown for best-selling 2D Zelda, so I was wrong.
Speaking of which, I never thought I'd see the day where Zelda would outsell Pokemon of all things. What alternate dimension are we living in?
