A strange little side quest
There is a neat bit of history hiding behind the kind of play you find in Celebrity Pedigree. In 1958, Tennis for Two used an analog computer and an oscilloscope to turn simple physics into a playable tennis-like demonstration. The timeline takes another interesting turn: Midway's Gun Fight from 1975 was the first arcade video game to use a microprocessor. It is a good reminder that simple game mechanics can carry a surprising amount of history.
