I can't remember if Myst was my first PC game.  I know it was the one that got me hooked--to the point where I kept upgrading computers and peripherals just to keep up with the games.  I tried to replay Myst a year ago and found I couldn't figure it out (have I lost that many brain cells over the years?), didn't have the patience or something to keep at it.  But like a first love, I remember it very fondly and treasure it.  It's almost heart breaking to think that some day soon, as Windows continues to do upgrade to different styles of OS, newbies won't be able to experience Myst.  Just like so many young people will never know how it felt when rock'n'roll burst forth.  To confess, I liked the graphics in Riven better.  And I never liked Artus (whatever) or his two sons--thought they were all slackers and whiners with serious emotional problems.  I loved that you could not die and nothing attacked you--really allowed [me] to explore and indulge my curiosity.  Loved the details (little bugs that moved, atmosphere, just everything).  Sound effects and "music"--wasn't Myst one of the first to put visuals and music together?  All in all, many good things started with Myst.  I know it was the first computer game that spent time and money on the graphics (something I always appreciated).  At most places, the game play wasn't strictly linear so you could play in whatever order you wanted.  You could "spin" around and see everything.  It was totally mouse driven.  One feature I loved (but many others complained about) was that it was an empty world, you never had to/got to interact with anyone else in Myst; for me it was somewhere of my own where I could explore to my heart's content, go back and walk around areas that I liked (like "tree" world (can't remember it's actual name) even after you finished that level.  It is an all 'round beautiful game.
