My first encounter with the concept of fantasy (not counting faery tales and fables) were with the Intellivision video game system from Mattel. I clearly remember walking through damp, dim, torchlit corridors in "Swords & Serpents", and being scared by the roar of the giant skeletons and giant ghosts in the castle dungeons of "Treasure of Tarmin".
As technology progressed, we got rid of that system and those games, but the memories remained. In a recent bout of nostalgia I re-aquired those titles. Imagine my surprise when my adult eyes saw what turned out to be very, very rudimentary graphics, compared to the very vivid images I carried in my mind.
