Way back in the olden days, Myst was known colloquially as the “shiznit.” In 1993, a video game with rendered, ray-traced graphics that brought the reader through a magical world of Steampunk-inspired puzzles and mysteriously-worded letters from your uncle. The game was launched the same year as Doom and I assure you that Myst was on par with that proto-FPS in terms of popularity.
Sadly, I missed most of the Myst but but I just downloaded the $5.99 iPhone app. Maybe I, too, will be able to wander aimlessly on an island.
