Reviewers were polarized. They praised the game's focus on fast gameplay and noted its similarities to the series' original 2D entries, a choice that some considered an improvement from the "Sonic Adventure" games. Reviewers also highlighted its graphic design and detailed environments and textures. Critics, however, derided the game for not addressing the problems of previous series games, such as poor camera, controls and voice acting. Despite mixed reviews, the game was commercially successful, with 3.41 million copies sold by 2007.
