Though Sega were keen to back the Xbox and GameCube upon release, the company's plans for the PlayStation 2 were subdued during the early years, receiving only a handful of Dreamcast conversions (including
F355 Challenge,
Rez,
Ecco the Dolphin: Defender of the Future and
Space Channel 5). Starting with the likes of
Gungrave in late 2002, PlayStation 2 exclusives from Sega began to pick up, but never to the same level as the console's rivals. By the middle of the decade Sega prioritised multi-platform releases, the PlayStation 2 receiving its fair share of titles, and the longer lifespan of the console led to the PlayStation 2 receiving the most Sega-published games overall.
Games like
Virtua Fighter 4 and reboots such as the
2005 release of Altered Beast and the
2002 release of Shinobi were made exclusive to the platform, and Sega found itself producing several "budget" releases for the console, such as the 33-volume
Sega Ages 2500 series. It also partnered with western publishers to release the likes of
Destroy All Humans! and
Killzone in Japan. The popular
Yakuza series began its life on the PlayStation 2 before continuing on the PlayStation 3, though much of Sega's top PS2 output came after the demise of the Xbox and GameCube.
In Europe, early Sega games were published by
Sony Computer Entertainment, possibly due to Sega's difficult financial situation. This was ammended by the latter half of 2002.
In Japan it was almost mandatory to support the PlayStation 2 as a third-party publisher, and particularly after the merger with
Sammy, Sega found itself supporting the PlayStation 2 well into the next generation. Sega's relationship with the PlayStation 2 could be considered a marriage of convenience - more "cutting edge" games from the company were given to the Xbox, while family-orientated games were brought to the GameCube. Nevertheless, Sega supported the console until 2008, with over 150 games published for the platform over a seven year period.
One of Sega's most important contributions to the PlayStation 2 library was the
Sega Ages 2500 series of remakes of classic Sega games. Originally created as a partnership with
D3Publisher, the series featured remakes and emulations of a wide variety of Sega games as early as
Head On and as recent as
Dynamite Deka, making it one of the most comprehensive compilation series produced by any company to date. Though the series would only be released in Japan, Sega brought a handful of the early volumes overseas in one package,
Sega Classics Collection.
Sega's
WOW Entertainment also produced
Vampire Night, a game for
Namco that runs both on PlayStation 2-based arcade hadware and on the PlayStation 2 itself.
