In 2000 the Hero Wars Rules were released along with several supplements over the past couple of years.
The new HEROQUEST system is a refined version of Hero Wars.
Personally I love the game..it's very rules light and very fun because as a player you pick and name abilities skills, magic items, etc for your character using a narrative process. Some peopl don't like the lack of concrete definitions for everything, but IMO it makes for a much more interesting story and there are lots of cool suprises for everyone involved, not just the players.
At any rate, I'm very much looking forward to the re-vamp as there were a few quirks within the original system.
