The original collection includes four games from the Dreamcast: three which were also part of the Sega All Stars budget range, plus Space Channel 5: Part 2, released simultaneously for the Dreamcast and PlayStation 2 in Japan, then later released exclusively for the PlayStation 2 outside of Japan. All games released in the bundle are available for purchase separately on the Xbox Live Arcade, PlayStation Network and Steam.[1] A retail release was originally listed for release on the PlayStation 3 but it was put on hold.[2]
Dreamcast Collection was later reissued on July 22, 2016 for Steam, adding two games, which are a part of the Sega Heritage Collection.[3] It was updated once again on April 7, 2020 to include Sonic Adventure 2, which completes the collection.[4] The games can be purchased either collectively or individually on Steam.
