• Accurate, motion-captured physics.
  
• Emulation of the table's control CPU for fully authentic reproduction of game rules and response.
  
• Highly-detailed 3D rendering of table features and artwork.
  
• Addam's Family and Addam's Family Gold modes.
  
• Supplementary multimedia material on the Addam's Family Pinball phenomenon.

I think the project was somewhere around 8 or 9 months in (counting pre-production) when it was cancelled. The were three main components of the game: graphics engine, physics engine, and emulation of the CPU that ran the board's LED and game logic. The emulation was functioning for both the original and Gold variations of the chipset. The physics was playable and had been married with the emulation, so that the game could be played and the bumpers, etc. would cause the expected responses on the LED. The physics was still in its testbed, however. You can see the testbed in the thumbnail on my site.

In the testbed, there was a greyscale "topographical map" of the board from a straight-down bird's eye view. Collision geometry was superimposed on the relief map in a wireframe, and the balls were basically colour coded icons. A second window would show the LED status, and a third window was an array of checkboxes that showed the state of all switches and lights in the pinball hardware.

The graphics models were complete, but had not been integrated with the other pinball code. There was very little work done on the graphics engine at that point, as focus was on getting the physics accurate and efficient.

So, it was playable, just not commercially pretty.
