First things first: Sorry
@Old Hob for derailing your thread not once but twice now! First with Talisman and now HeroQuest.
It came out when I was in my mid/late teens. I decided it was aimed at little kids and ignored it. From everything I've heard since, I missed out on a banger.
HeroQuest was very much the gateway drug to miniatures for a certain generation and GW definitely made its name and miniature wargaming in general known to large crowd of potential/future customers with it. Rules are simple (oddly they're more complicated in the US version, I believe? ManicMan will fact check me on this one

. ) and I don't think your assumption of it being aimed at younger kids is totally off, but it was (and still could be, I mean why not?) fun one to spend some time with friends, only now as adults it would be more of "shoot the **** and down some beers" kind of deal for me, I think.
Advanced HeroQuest is a bit too advanced for me, and while I have the game and Terror in the Dark and would like to give it a go some time, I've become old and lazy and can't be bothered reading all the rules. Seems like a cool game, though, and way more complex and closer to TTRPG experience than original HQ was. I'd say WarhammerQuest was the final form in evolution of HQ and Mordheim was more "Necromunda but fantasy".
no-comment on the modern re-issue of the USA version with really bad miniatures... I think that has no place in a sensible talk like this.
"Is that your final answer?"

Just kidding. It's not exactly Oldhammer kind of stuff and I've got no idea how it plays like (pretty much the same as original but without fimirs, I guess) but if another generation gets to experience the same that you and I did as kids, let 'em have their fun.
I did dig out my copy of HQ to replace photo of monster card by one I took (not going to do it now since it would break Old Hob's quote) and, while at it, had a look at some other translated board game gems of the era. Wow, did it feel surreal seeing all were made in europe. Wonder if Talisman and The Warlock of Firetop Mountain were made before or after German reunification.
Now redundant photo of monster card:
Them good old games from way back:
