Although I haven't had as much game time as usual lately, I was able to sneak in a few sessions with Ghostbusters: The Video Game on PlayStation 3.
I haven't checked any FAQs, but I'd estimate I'm about halfway through or so—before I started, I was hoping that the game would be at least decent, but I'm quite glad to report that it's actually fantastic. Without a doubt, it's certainly among the best license-based games ever created, if not the best. Besides that, it's great just as a game, license or not.
Although I certainly think anyone would be able to enjoy the action, I'd guess that it's at least twice as good for people (like me) who are fans of the film.
