Initially released in Japan to a subdued reception, the Dreamcast enjoyed a highly successful U.S. launch backed by a large marketing campaign, but interest in the system steadily declined as Sony built hype for the upcoming PlayStation 2. After a change in leadership, Sega discontinued the Dreamcast on March 31, 2001, withdrawing from the console business and restructuring itself as a third-party publisher. Its game library contains many titles considered creative and innovative, including Crazy Taxi, Jet Set Radio and Shenmue, as well as high-quality ports from Sega's NAOMI arcade system board.
