The game received universal acclaim from reviewers and was Nintendo's top seller during the 1999 holiday season, with 2. 3 million units sold by 2004. It won the 1999 E3 Game Critics award for Best Platform Game, and multiple awards and nominations from games magazines. Reviewers noted the game's exceptional size and length, but criticized its camera controls and emphasis on item collection and backtracking. Some cited its similarity in gameplay and visuals to Rare's 1998 predecessor, Banjo-Kazooie, despite Donkey Kong 64's mandatory memory add-on. Critics felt that the game did not meet the revolutionary potential of Donkey Kong Country, but remained among the best 3D platform games on the console.
