One of the best early games based on a movie. Ghostbusters
begins with a bank loan as you start your own franchise,
buy ghost traps and a vehicle, and start catching ghosts.
Most of the game is spent catching slimer type creatures
as the city's PK energy rises, then if you've made enough
money run underneath Mister Staypuff to cross the streams.
The C64 version makes great use of sampled speech.
