Initially, the game received a somewhat negative impression in Japan. Parts of the game were alleged to be buggy, and the game refused to work at all in older SCPH-10000 PlayStation 2s. Enix blamed Sony, as they had coded Star Ocean 3 with features from updated libraries that were apparently not backward-compatible.[1] Sony denied all responsibility. Regardless, it impacted the game's sales, and Enix released the Director's Cut in 2004 to assuage grievances about the original by fixing the bugs and adding features. In North America, the game was well received among both critics and players, with Game Rankings, a compilation of critical reviews, giving it an average score of 81%. Star Ocean 3 was the 96th-best seller among console games of the PS2/GameCube/Xbox generation as of July 2006; it had estimated U.S. sales of 630,000 copies, with revenues of $23 million.[2] In Japan, the original sold 533,373 copies as of 2003,[3], while the Director's Cut version sold an additional 416,859.[4]
