Ghostbuster 3 or the next best thing

so the sequel to the original Ghostbusters wasn't nearly as good as its predecessor and we've yet see all of the original cast together in a movie again, especially considering bill murray is the only one still making good movies, but it looks like they are all together again at last. i suppose its possible this game could even been better, if not at least a substitute for the 3rd movie that will probably never come.

there's a rather short trailer that shows next to nothing.


oh and not sure but there might also be a cgi movie coming out as well, not sure if they will have the same story or not.
