I'd rather see the pinball manufacturers concentrate on making "new" machines rather than try to remake old titles. If MM or AFM were rare like Pinball Circus or Kingpin it would be one thing, but as it stands I see these games in collections or on route as much as if not more than most other games of this era. I'd be much more prone to buy a JJP Hobbit or WOZ than I would a NIB AFM or MM at a $6500 price point.
If a company like JJP were to take on such an endeavor wouldn't it make sense to make an improved version or sequel of a game like AFM. If you make a version that is identical to the original version you limit yourself to the people that don't currently own the game and have $6500 or more to spend on a game. Why not add some special modes and modify the code to work with the new boardset and an LCD screen. -Similar to what Jackbot did to the Pinbot design by adding a DMD. You could even keep the playfield the same to save on R&D costs. Or you could do some subtle tweaks as was done to the "Attack and Revenge from Mars" design that was done in Visual Pinball.
