Cyan has stated that Myst ME is going to be on Steam soon, id wait for that, Real myst is a bit glitchy and a resource hog, even 10 years after that came out.... XD, I cant imagine trying to play that when it came out.

I got all 3 books , and the soundtracks, and cant wait for the movie to come out http://mystmovie.com/2010/07/31/well/
however I have yet to beat riven, took me 16 years to beat Myst...
