 Overall, critical reactions of the game were varied; its features did not have universal appeal. Wilde argued that only rabid fans of the themes incorporated in Project Sylpheed would be interested in the game. His colleague, Geson Hatchett, felt the game would have been better as a rail shooter with 3D graphics. The general sentiment among reviewers was that Project Sylpheed could not spark a revival of interest in a long-dying genre regardless of whatever qualities it may have. Despite receiving such reactions, Project Sylpheed sold enough copies (as judged by Microsoft) in Japan within the first nine months of its release to become part of Xbox 360's Platinum Collection on November 1, 2007.
