Yeah but you have to think whether 3d would do much for them . I think bombjack would be hard to see where you are going.

The more simple elements I already extrude to a fixed thickness. More compilcated ones could have a big lookup for tile number to model. These could be both quite generic. Though you still have the effort of generating all the models in the first place.
The only difficulty is in doing tricks with the camera. eg Ive made the maze movable but the information text stay in place. This is done by identifying which tiles should be fixed or movable. I suppose that could be made generic but is the effect something you would want on a different game.
Or the first person perspective mode. Here you need to identify the pacman sprite, its location and the direction its facing in (which is worked out through sprite numbers and whether it has been flipped). Making that generic would be much harder.
