Same for me. At that time, the 'drm' of games often consisted of a physical thing that let you solve some sort of puzzle at startup. For example, for monkey island, there were two discs you had to rotate to a certain position and then enter a certain symbol it would produce.

Anyway, for many years, I just assumed that it was the same for leisure suit larry; and that I was just missing the papers. Many of the questions didn't make sense to my (Belgian/Dutch) parents. At some point, they started questioning why we were asking all these questions, so we had to find another way to figure them out.
