Myst is an iconic graphic adventure game that was first released in 1993 on Mac OS before coming to Windows the following year. The game was a huge success, becoming the best-selling PC game of all time - a title that it held until The Sims was released and eventually exceeded its sales figures. Myst's success was largely down to its memorable main island, which looked incredible for the time, and its well-designed puzzles that were smartly integrated into the environments.
