Hitchhiker's Guide to the Galaxy text game was my first. Dad brought home an Apple ][+ from work when they upgraded and we went to the Apple store for advice and saw games! The Hitchhiker's box intrigued me (I still have it) and that was the beginning. The first graphic adventure was Myst that came with a shiny new PacBell and I was thrilled.
It was all downhill from there.
