That is not only true for games, but for all software in generals. For most people old productivity software are meaningless, but they are part of history, the same way games are and they deserve to be archived properly too.
It is possible to find here and there disk images with a scan or shot of the medias (of very different quality). For my part, since I decided to archive my software collection, I made high quality shots with controlled lighting of my boxes and media. Unfortunately I haven't done the papers inside (manuals, warranty cards, maps, etc) because a lack of time.
There is a catch with some 3.5" floppies disks though as some labels are directly printed into the disk case, some have sticker with gold, silver or hologram effects. They are impossible to acquire correctly, not speaking of redoing them.
Also, some floppies have colored cases, that is a part of the identity of the program as the sticker is.
Knowing things is great. Understanding things is better. Creating things is even better.
