Great price for a really fun game.
A little bit about the game -
The game features an all new storyline but still manages to replicate most of the major scenes from the films, including the hotel-room capture of New York library ghost, Slimer, and the attack of the Stay Puft Marshmallow Man. Almost all of the original cast are involved, including all four Ghostbusters, the mayor, and even Walter Peck.
The game itself is mission based and has you catching ghosts with your proton packs and then manoeuvring them into a ghost trap--just like the movie. Whether thats enough to fill a whole game isnt clear, but the funny dialogue and celebrity voiceovers should help paper over any cracks.
