Comment 2 for bug 574115

amgine, you should use Shift-Command-S to save games in future (Save as...) instead of Command-S (Save and overwrite). This gives you the opportunity to name your game. I use a 2 number prefix followed by a brief description, so that I can easily see the sequence of saves, although you can also list by date order in the Save dialogue box, which more or less achieves the same result!

Then you can retrace to a place before you made a mistake easily.

The Save box drops down when in full screen mode if you use Shift-Command-S

Re: the other Myst games, I've read a comment by Jean-François that he has no plans to work on those.
