Restoring dead floppies

So, I have a large collection of vintage Mac games, something in the
order of 160 or so, most of which are "big box" games, about half of
which are CD-ROM and the other half floppy disk. Sadly, but inevitably,
many of the floppy disks are now dead; they do not mount to desktop.
Seeing as they're all 30 or more years old, it's no surprise that disk
rot has finally got them, but still a bit sad.

It did make me wonder, though, is there any value in going to the
effort to restore the disks? I mean, I know the answer is "No, none
whatsoever" but... the idea that these games are now little more than
ornaments on my shelf rather than actual useable software depresses me
a little.

It should be trivial to find digital back-ups of these on the web but
are these disks physically beyond use now, or is it just data
corruption? If I were to format the disks, would I be able to place the
software back onto them?
