If I remember correctly, the computer game HeroQuest was based on rules from a tabletop RPG. Does anyone know which RPG's rules it was based on?
It was based on the classic Games Workshop / MB board game Hero Quest. (This was one of the better GW releases of the era.) GW released an Advanced version which came closer to roleplay; it allowed for a GM and some ability development. Still clearly a board game though.

\$\begingroup\$ I played the board game back in the day. It was more or less a tabletop RPG played as a board game, with relatively fewer rules and less DM fiat, since there were only a limited number of things a player was allowed to attempt. I think there were less than 10 spells total in the game that one could learn, and maybe half a dozen weapons. \$\endgroup\$ Jun 18, 2020 at 18:17
The HeroQuest computer game is an implementation of the GW/Milton Bradley board game, Hero Quest.
It draws heavily from the shared tropes of the Warhammer line of games, including Warhammer Fantasy Battle and especially Warhammer FRP. It shares some minor mechanical similarities with WFRP, but is not actually the same system.
There also was an Advanced HeroQuest. It used a similar ruleset and compatible components, but was more involved.
The whole HeroQuest system is out of print.
There is a HeroQuest RPG, but it's unrelated to the board game, being instead related to RuneQuest. It is currently in print in a 2nd edition, it's first edition being the revision of the slightly older version called Hero Wars.
