Obviously, crediting a "Director" was borrowed from the cinema industry. It was a new trend in computer game development in the late 1980s and early 1990s to embrace the story-telling aspect of a movie within games.
I'd point to the aptly named "Cinemaware" games beginning in 1986. And the trend grew stronger with the rising popularity of CD-ROM and full-motion video as providing the necessary storage and playback to introduce more cinema like content to a game.
Origin's "Wing Commander" was an early (1990) game that embraced these concepts and also credited "Director Chris Roberts" in the game itself.
When did this job title first appear in the credits for a video game? Who were the early/famous Directors, and what were they expected to contribute to the game development effort?
