Heroquest is a game better remembered than played, I think. The worst aspect is that monsters only have 1 Body Point (even the Gargoyle) and there's only 1 evil Shield icon on the combat dice. Advanced Heroquest, on the other hand ...
Dammit AndrewGPaul... you've finally forced me to register on Dakka to rant about HeroQuest! SERIOUS BIZNIZ, I tell you.
I take your point about family playability (the original UK
TV advert featured a load of kids who looked about 10; "Fire of Wrath" is one of those cathphrases that was compulsory in our games). From my point of view, I think I first played it after
having played Advanced Heroquest, during a rainy summer holiday. The exploits of Grungni fimir-flattener, Legless the Elf and a Barbarian and wizard with forgettable names are legendary, although I, as Morcar spent a fortnight watching my minions get repeatedly butchered. Perhaps if we'd played Heroquest first, it would have been OK.
That's why I say it's best left as nostalgia - it [is
a great game when you're a kid, but now that you're an adult, don't sully those memories by actually playing it again.
