I have been a fan of Ghostbusters since I was a kid and saw the movies for the first time back in the 90's. I didn't actually play this game until this year, but I'm glad that I checked it out.
You play a new addition to the team named Rookie (they don't want to bother to learn your name). You will work with the rest of the team, voiced by all the real actors, and fight hoards of ghosts. This game is actually considered to be the third movie and is a continuation of the first and second movies. So rather than spending you hard earned money going to see that new "movie" (using the term lightly), spend it on this great game and know that you didn't completely waste your money.
