And it was apparently good!

Published in 1986, Ghostbusters: A Frightfully Cheerful Roleplaying Game went on to win the H. G. Wells award for Best Roleplaying Rules of 1986.

It was a very simple rule set based around the idea that you just purchased a Ghostbusters franchise and are based in a city other than New York. Your character sheets are called Ghostbusters ID cards and can be found here. The game was revised and re-released in 1989 when it was renamed Ghostbusters International. It’s wobsite and scans of the rules can be found here and here.
