Dunjonquest: The Datestones of Ryn

You, Brian Hammerhand, mercenary at large, presently least senior officer of
the cavalry troop, and drawer of the shortest straw, have the singular honor
of undertaking this hazardous but glorious mission. Will you emerge
victorious, carrying the sacred stones and the head of Rex the Reaver, or will
you meet ignominious defeat, pierced through by a cold steel blade thrust from
the shadows? The honor of the duchy is in your hands. A 2D text based RPG
written in BASIC.
