Any fans of the classic puzzle adventure Myst out there? GOG.com has just released Myst: Masterpiece Edition as a digital download for just $5.99. Myst was originally released in 1993 and was the best-selling PC game for years until The Sims took over the charts. Masterpiece Edition is an updated version released in 2000 that includes enhanced graphics, sound effects and cinematics; digitally remastered audio; and a built-in guide that offers hints, tracks your progress, and makes the game more accessible. Riven: The Sequel to Myst is scheduled to come out on GOG.com soon as well, also for $5.99. If you do decide to download Myst, write a review and let us know what you thought of it!
