I'd just begun my first professional engineering job after college. The company I was working for had a mainframe computer on which there was a copy of Adventure. When I discovered the game, there were a number of late nights playing it. One night, long after everyone had gone home, I was playing in my office with the lights off. The only light was from the green phosphorous monitor I was using. All of a sudden, I stumbled into the breath-taking view room with its erupting volcano. The words describing the scene filled the screen with descriptive prose that simply glowed in the dark room. The effect was mesmerizing. Forty-seven years later, I've never forgotten that.
