(written from a Production point of view)
Sega Corporation is an international video game software and hardware development company, and a former home computer and console manufacturer. Founded in 1940 as Standard Games (later Service Games) in East Palo Alto, California (later moving to Japan in May 1952 as "SErvice GAmes of Japan"), the company has had success in both arcades and the home console market. In early 2001, they left the consumer console business and began concentrating on software development for multiple platforms.
Sega is best known for creating video games such as Sonic The Hedgehog.
Sega produced only one Star Trek-related arcade game, the Star Trek: Strategic Operations Simulator video game. They also marketed a version of the game for several home game and computer systems. A Sega game for the Atari 2600 based on Star Trek III: The Search for Spock was under production, but was canceled and never realized.
In addition, Sega produced several home systems of their own. Of these, only the Sega Genesis/Mega Drive, Game Gear and 32X had Star Trek-related games produced for them. A port of Star Trek: New Worlds was announced for the Dreamcast but it was cancelled and never released.
From 1993 to 1994 they also maintained a video game content rating system known as the Videogame Rating Council which rated games released on Sega platforms in North America before it was phased out in favor of the Entertainment Software Rating Board system.
