You will feel like a Real Ghostbuster - unless you like to save your game.
My BIG complaint is you CANNOT SAVE DURING THE MISSIONS! They are laid out in stages/checkpoints. Didn't they learn anything from Star Wars: Dark Forces? Time is not on my side and I must interrupt gameplay and call it a day at last minute notice. No way in hell I'm leaving my 800 Watt dual quad-core XEON workstation idling for 8-10 hours while I have to leave unexpectedly. My electricity bill would be outrageous and my computer would be doubling as a space heater in the hot summer weather.
Overall I applaud the designers and cast for creating a true feeling of being a Ghostbuster. If they would have created an option to save games during a mission, I would have given this game a 9.5, I would recommend this game for those who have time on their hands who don't mind having to complete the missions without the luxury of saving a game.
