all videos i've seen and write ups on the game is you play as your own character the 4th ghostubster. You can't play as the other main actors.
You are a bit wrong. As any real fan of the Ghostbuster movies could tell you. You actually play as a 5th Ghostbuster, remember there were 4 of them in the movies, and all 4 of the originals are in the game.
Seeing as how much respect I have for Bill Murray, its got to be Winston for me. He was always the odd man out and I relate to him a lot better than the scientists.
Well from what I have read at many sites is the only two from the movies that won't be apart of the game are Sigourney Weaver and Rick Moranis. Of course Rick's excuse was that he did not need the money, which does not fly as I am sure Bill Murray doesn't need the money either and he is doing it.
