Cyan Worlds/Myst - Best single player games ever. You are placed into a particular world to solve mysteries to advance to the next level. Graphics, sounds and challenging environments propel you into unbelieveable scenery, simply the best real life games ever coded. I own the complete boxed series, but find the versions on GOG easier to play, because there are no discs to replace when you advance to thenext level. And you save a lot of $$$ .
