For some reason the game only saves the current point, the saved game Options are all blank, so if I make a mistake, I can't go back to a previous save. I was at the very end of the game and accidentally clicked the wrong object, with undesired results. Had to work the whole game over again to get where I was. I think I was having problems with saves before the recent game update, but I'm not sure, since I hadn't tried them (there were not pictures in the "Saved" boxes). I'd wanted to test the game's alternate endings, but I don't want to play the whole thing over two or three times.
I have been wanting to replay Myst for about 10 years, even had a friend load Windows 3.1 to a computer, so my disc would work, but the clunker died before I got too far. I found out about RM:ME during the Obduction Kickstarter, so I finally got my chance for a replay! Thanks, CYAN. Next I'm going to see if my old RIVEN discs still work!
