I think it would kick ass.
have any of you played “Die Hard trilogy 2”? there's 3 different kinds of styles to the game
1: first person/shooting mode
2: third person/explore-n-shoot mode
3: driving mode
take those elements, and do the same thing for a Ghostbusters game, (but of course, tweak it.) commercilize it like nuts, and the game could be bigger than cheese sauce on curly fries!
