Before AVGN I didn´t know there was an NES version. The biggest problems of the NES version seem to be that is a more or less direct port of the C64 version (but was released 5 years later thus looking and sounding real dated) and that it adds a very difficult level. The staircase and final battle were absent from the C64 version. Once you got past Stay Puft Marshmallow Man the game was over.
Basically the C64 version consist of buying equipment and making money by catching ghosts in your trap and on the trap on your cars roof in the driving stages.
I guess it was pretty good for the time(1984). It was by the same guy who did Pitfall I think. It was one of the first games I ever played. But I guess for a 1989 Ghostbusters game on the NES you could have expected a bit more. They must have rushed it out to conincide with the second movie (that it isn´t even based on).
