This sounds exactly like the old 8-bit Ghostbusters game, the "best" version of which can be found on the Sega Master System. That game involved driving and action sequences during ghostbusting missions. We don't know yet how much action will be involved in the new version, whether it will be a remake of this game or an expanded strategy/tycoon-type game.
The timeline is different, occuring after Ghostbusters II rather than during the first movie (which means no Keymaster and Gatekeeper wandering the streets). We hope the gameplay is different in some significant way from the original game, at least in the "being profoundly terrible" department.
