After all we grew up with our computer worlds already pre-formed into the conceptual continents of Apple OS, UNIX, and Windows. The more historically curious among us are vaguely aware that other island cultures do exist but they represent civilizations defeated in the marketplace. Explorations into these ancient worlds resemble documentaries about archeologists decoding rediscovered languages etched in stone.
