One early Infocom computer adventure game, put snackmosphere into the packaging so you smell ancient air when you open it. Part of their copy protection was the need for certain implements in the package to get going in the game.(combinations to open the GrandMaster's trunk so you get the tools you need, or to even get out of the mansion and start your search for the missing GrandMaster) and the combination differs each time you play.)
I'm going by memory as it has been years since I last had a working Apple ][ (over 25 years) which Infocom games were written for.

As you said on DeviantArt. It was an era when copyright protections were beneficial to the game experience instead of hindering it.
Back in the '80s, my family didn't have any Apple products and thus no Infocom. What we did have were Tandy's CoCos (Color Computers) and a subscription to Rainbow which printed a number of programs (mostly utilities –yawn–) that had to be tediously typed into the computer. (Later, a floppy disk with the programs were included.) So what was my earliest computer "games" I got to "play"? Math problems.
