Ghostbusters was developed and published by Sega for the Mega Drive/Genesis in 1990.

Main article: Ghostbusters (1990 video game) The new ending in the NES version is full of spelling, grammar and punctuation mistakes: The game varied in some respects depending upon which platform it was played the Sega Master System version (1987) added an on-foot shooting gallery level with different animations, while the NES version (1988), ported by Japanese developer Bits Laboratory, made the action sequences considerably more difficult, had lower graphical resolution and provided a different ending.

This allowed accelerated progression in the new game. Upon completion of the Commodore 64, ZX Spectrum, Atari 8-bit, Amstrad CPC, Sega Master System and MSX versions of the game, a code was provided that allowed the player to start a new game with the amount of money accumulated by the end of the previous game. The game starts with a choice between four drivable cars, and the player must stock up on equipment and make money to complete their objectives. The game was later ported to the ZX Spectrum, Amstrad CPC, MSX, and Atari 2600. The last week of development was spent on the opening screen which plays the Ghostbusters theme song. While pleased with the game, Crane later stated that he regretted not being able to include a better victory screen. Activision obtained the license early in the film's production, and most of the game was finished by the time Crane watched the film. He based it in part on an incomplete game called Car Wars featuring armed automobiles in a city this led, for example, to the "ghost vacuum" on the Ecto-1, something not present in the film. Most versions of the game have a similar basic format to the initial Commodore 64 and Atari 8-bit family game, which Crane wrote in six weeks.
