In 1986 West End Games published Ghostbusters™ A Frightfully Cheerful Roleplaying Game. One of the things this one of a kind Ghostbusters game book came with were ID cards for the Ghostbusters, Janine, and Dana. Sorry Louis.
That was pretty much it, (that I know of) until a new Ghostbusters movie was released during Summer 2016.
If you or your RPG buddies have been waiting to add the newer Ghostbusters and didn’t because of lack of equipment cards the wait is finally over.
