From many accounts (except for Wayne's) the game functioned and presented very very well.
It took Nug and me maybe ten minutes to tweak a couple of things like the odd switch or two, but that was it - very little to complain about. It was presented as a collector would have expected for a collector type game. In almost ten years I have not had any faults at all. Not a single one I can recall, the build quality was exemplary.
I know someone who shall remain nameless that decided that a coil was physically upside-down which cause an electrical issue so that something would not work properly......
