The premium at the MoP was dialed in fairly quickly. The LE however has had issues since it came out of the box, including cheap drains and the machine failing to find the ball and going into ball search. Several techs have looked at it with no luck.

I think the game is like SW....it was a dream theme for a lot of people and those people wanted stern to make those 2 titles perfectly
Stern dropped the ball on these 2 and those who could not wait for their release seem to be dissapointed now that they have them (I know, not ALL buyers feel this way)
I doubt there a more than a handful of buyers who sold GB because the designer is an (alleged) scumbag.

This is why the game does not dissapoint you like it does so many people...
