I think the posts from LostAmongtheBarrens have renewed by curiosity about Hero Quest. I have WHQ and AHQ but for the circle to be complete I need HQ! It's amazing how many people I run into tell me about HQ when I talk about D&D / RPGs or dungeon floor plans.
As Mortis will tell you, there's always a something HQ-related on Ebay - especially "spares".
I was bidding on a "complete" game which started at about £10 before postage.
It was a tough fight and I bailed when my highest bid of £36.03 was trumped. The silly thing went for about £37 in the end. The joke is that I'm mainly interested in the rules, dice and character cards.
The good news is that I managed to buy 1st edition Rifts for almost nothing and even better (although it's yet to arrive) for a few pennies over a tenner: a Basic D&D (Red '83) set with two floor plan sets and 2nd AD&D Ravenloft boxed set (for which I partly blame Mortis and a gamer friend who has a thing for vampires.)
So if I get addicted to Ebay again it'll be the fault of LostAmongTheBarrens.
