Outback

Outback is linked here to the Game Boy game Hiden Inyou Kikouhou: Ca Da. Developer-credit research assigns planning and production to Outback, while separately naming Thinking Rabbit for development and Party Room 21 for Japanese publication. The catalogue's broad development link records project participation, not sole responsibility for code, art or publishing. It counts one canonical title. The historical research entry remains a work in progress, so this project credit does not establish the company's complete staff structure or catalogue.

OpenTTD Team

OpenTTD Team denotes the people maintaining the OpenTTD project. An official project post refers to the OpenTTD Development Team, while Steam credits OpenTTD for both development and publication. The game centres on building and operating road, rail, water and air transport networks and continues as free, open-source software. This profile records the one canonical game linked here without treating the team name as a verified incorporated company or attributing the original Transport Tycoon Deluxe to it.

OVERDRIVE

OVERDRIVE is linked here to one canonical game, Deardrops Distortion. Japanese PlayStation Portable edition records identify Over Drive as developer and CyberFront as publisher. The title adapts an earlier PC visual novel, following a story centred on music and a band. This profile states the supported PSP development connection, without transferring CyberFront's publishing role to OVERDRIVE or assuming that every change in a port was completed independently by the original team.

Overplay

Overplay is linked here to the Nintendo DS game Beauty Academy. Its original credits contain separate Overplay sections for development, art, audio and design; Tivola's creative and project-management credits are listed apart, and release information identifies Tivola Publishing as publisher. The game centres on running a beauty studio and completing customers' hair and make-up tasks. This catalogue records one canonical development association, rather than transferring Tivola's publishing role to Overplay or counting the DSi and 3DS editions as additional games. The credits document this project's staff roles but do not establish the studio's founding date or every business partnership.

Oxford Softworks

Oxford Softworks is credited with developing the Japanese PlayStation game Backgammon 2000. Two independent platform-specific release catalogues name the studio as developer and Unbalance as publisher, with the Japanese product record attached. This catalogue currently counts one linked canonical game. Founding and closure dates in an older generic description were not independently confirmed during this game-credit review and are therefore not repeated as facts.

OUAT

OUAT Entertainment is linked here to one canonical game, Allez Raconte. Nintendo DS edition catalogues and contemporary retail information identify OUAT Entertainment as the developer and Bigben as publisher. The game combines interactive storytelling with activities aimed at younger players. This profile records the supported development relationship and normalizes an earlier shortened English display name, OUAT, to the canonical company name. The short form does not establish a separate entity, and Bigben's publishing role is not assigned to the development studio.

O-TWO

O-TWO Inc. is linked here to the PSP game Antiphona no Seikahime: Tenshi no Score Op.A. Independent game listings identify O-TWO as developer and Nippon Ichi Software separately as publisher. This catalogue counts one canonical game for the development relationship; it does not transfer publishing responsibility or other related games to the studio. The reviewed credit supports this specific contribution, not a founding date, headquarters, or complete corporate history.
