England in the Middle Ages is seeking a King. Knights from across the land go on exciting and adventurous quests with one goal in mind: to pull the sword Excalibur from the stone and claim the throne. As in the story, the game lets players take the role of knights wandering from town to town and adventure to adventure. While doing so, they encounter the saga's heroes - bridge guardians, generous barkeeps, successful noblemen - who influence the events of the game. Their voices can be heard from the giant fist-sized stone that is fastened to the gameboard and in which Excalibur rests.
The electronics of the game pay attention throughout and remember every move of every player: Good deeds are rewarded and un-knightly deeds punished by friendly (or less friendly!) characters which speak to the players through the stone.
