Quoted from ForceFlow:
Although it's a lot of fun, it isn't an A-list title. From what I understand, years ago they were so incredibly unpopular that they were parted out for their boards, which is a large contributing factor in their rarity today.
I had a PERFECT one I took to CAX in 2006, had a $1600 price on it, and couldn't sell it. It was VERY unpopular until pretty recently.
Fun game, but it's a B title for sure.
