Even with no multiplay on the PC and an InstallShield/SecuROM bug that doesn't allow you to install the game anywhere but C: drive this game is simply awesome.
Many of the voiceovers are done by talent that will actually be in the third movie that is rumored to have a mid 2011 release date.
If you even remotely like the Ghostbusters movie then the game is definitely for you. Excellent. Great dialogue, completely destructible environments (I was shooting stuff just to watch it explode into pieces), great story, excellent ghost catching physics, and great graphics (at least on the PC version).
Usually games made after movies really suck but this one is a gem.
