My parents owned an first edition copy of MYST, and a 5 disc set of Riven. My Mom and Dad loaned our MYST disc to my Grandparents (some geography... My parents and I lived out in Western Canada (Saskatchewan), and my Grandparents lived by Ottawa (East/Central Canada), so we rarely got to see eachother), and so when I would go there with my Mom every few years, I would see it on the shelf. I tried it once, and I kept trying to move around with the arrow keys (hey, I was 8). Recently (December 2004), I got intrigued by the Riven box set on the top of our game shelf, and so I asked my Dad if I could install it. He said sure, but told me that there was a prequel (MYST). By then, my parents and I had moved back to Ontario, to the St. Lawrence Valley, so my Grandparents came out to Kingston for Christmas. I requested that they bring our copy of MYST with them, so I could play. They brought it with them, and on Boxing Day (Dec. 26th for the Americans, Boxing day for the British and Commonwealth) I installed MYST. I was a little put down by the graphics, but I went through the game so that I could start Riven. When I first saw the Brothers in the books, I thought there was something wrong with Quicktime, with all the static
I finished MYST, and it was one of my proudest moments. The first Age I managed to get to was StoneShip, and I was in awe. I knew of the technical limitations of the early 1990's (My Grandpa, a computer engineer, had ancient computer stuff all over his house), and recognized that these would have been cutting edge graphics when MYST came out.
When I finished, I immediately installed Riven, and completed that. The next Christmas, I got Exile, Revelation, and End of Ages for Christmas. That makes it so that the only MYST game I ever spent money on was URU. It might have been the best spent $20 in my life.
