Granted, the previous games were mostly created during the 1980s when the game industry hadn't yet found the magic formula for successfully turning a movie into a comparatively decent game. Today's movie-to-game projects typically benefit from the input of the creative crew responsible for the film. The participation of Dan Aykroyd, Harold Ramis, and Bill Murray put the new Ghostbusters game a step ahead of any of the previous titles before a single screenshot hit the Internet. The horsepower driving the modern consoles goes a long way towards bringing the experience one would expect from a proper Ghostbusters game. Legitimate thrills just weren't possible from the old 8-bit generation of hardware.
Hopefully if Ghostbusters lives up to its potential then we'll start to see more modern games based on classic films. I still have high hopes for an eventual Back to the Future game that honors the film trilogy instead of misunderstanding it completely.
