Although the game was nominally played entirely in text, it was also the first game to employ line of sight graphics displays. Its use of

Many schools viewed games as gimmicks to interest students in computers, but wanted only small, fast-play examples to minimize games' actual use to reserve time for math and science research and student use.

Years later (ca. 1980) DECUS distributed another game named ''Dungeon'', that was in fact a version of ''
