From the introduction: Isle of the Cyclops is the first in a proposed series of amateur fantasy adventure gamebooks, entitled Fabled Fantasy, given that two of their three core values have been appropriated from the Fabled Lands and Fighting Fantasy gamebook series. We’ll get to the third core value in a moment. In Isle of the Cyclops, as with any other Fabled Fantasy title, you can explore as you please. All you need is one die, an eraser, and a pencil.
