I received this game fro Xmas and I just have to say:
This game was AWESOME!
The graphics were ace, the controls were fluid, the weapons were innovative, and the story, while somewhat recycled and cliche, was good.
The voice acting is my only slight gripe. Dan Aykroyd and Harold Ramis did an awesome job. Annie Potts, also, did well.
Bill Murray's lines felt too forced, I guess. He just didn't have that magical wit from the first film, in my opinion.
Ernie Hudson, as much as I like his acting, did very poor in this game. His lines and expressions ("Behind you!", "Oh, no!", "Take cover, kid!", etc) were just as bland as can be.
Overall rating: 8.5
If you are a Ghostbusters fan, you will love this game. If not, it's definitely worth a rental, but not a purchase, if you ask me. I'll be messing around with multiplayer this weekend.
