Played BK and Gorgar in the mall arcade ("The Land of Oz") while my aunt was waiting in line (interminably) for tickets to "Empire Strikes Back". I had recently received the "Speech Synthesizer Module" for my TI99-4A computer as a birthday gift, so I was very enamored with the speech stuff and these games played right into that.
I say it was my "start" because somehow the stars aligned, and I put high scores on both machines that night; it's the point at which I started to "get" pinball beyond simply keeping the ball from draining.
