The media I copied from took up 28x 3.5" HD floppy disks. It's possible they were copied from what was originally a CD-ROM. I don't remember clearly anymore.
Note: I'm not trying to refute or correct your 13-disk figure, which was clearly a different installation set, and likely original Windows 95 rather than my OSR2, which came out around 1997.

Now I know why.
Edit: just checked in Google. Win95 was just 13 floppies. But you had MS Office and other software that was additional floppies to install.
We'll, still is, but in high school too.
Much easier these days with virtualization and COW images.
So potentially such drinking game could last longer than booze on hands.
xcopy /h/e/c/k/r/y c:\windows\system32\ c:\sys32\
attrib +h c:\sys32\
From a repair boot disk xcopy /h/e/c/k/r/y c:\sys32\ c:\windows\system32\
attrib -h c:\windows\system32\i installed windows 98 so many times i still remember the pirated serial number k4hvd-q9tj9-6crx9-c9g68-qr2d3
and then cdc's bo2k came out and everything changed!
