The games opening video runs well; full-screen, no unwanted cursors, audio/video in sync. Then when you get to the main menu (which is a full 3D environment) it runs fine. New Game leads to some VO during a loading screen which runs fine. However, at the instant you follow the Press Any Key To Continue prompt, you get a fatal exception.
Restarting the game gives a Safe Mode option. This lets you get past the point of the fatal exception above, but gives another when you get into your first gunfight.
So, there is literally no way to actually play the game, hence my Known Not To Work rating.
