In the years following the game's release, rumours spread that Miyamoto disliked Donkey Kong Country and found it amateurish, provoking him to create the hand-drawn art style of Yoshi's Island. He was allegedly quoted as telling Electronic Games magazine in 1995 that "Donkey Kong Country proves that players will put up with mediocre gameplay as long as the art is good".
Again according to wikipedia, DKC was one of the top selling SNES games, only Super Mario World and Super Mario All-Stars are higher on the list https://en.wikipedia.org/wiki/List_of_best-selling_Super_Nin....
