HeroQuest, sometimes also written as Hero Quest, is an adventure board game created by Milton Bradley in conjunction with the British company Games Workshop and set in the latter's Warhammer Fantasy fictional universe. The game was based loosely around archetypes of fantasy role-playing games: the game itself was actually a game system, allowing the gamemaster (called "Zargon" in the US, "Morcar" in the UK) to create dungeons of his or her own design using the provided game board, tiles, furnishings and monsters. Several expansions were released, each adding new tiles, artifacts and new monsters to the core system. Copies routinely sell on eBay for double or more of the original selling price, with rarer expansions in perfect condition reaching even twenty times the original rate
