A strange little side quest
There is a neat bit of history hiding behind the kind of play you find in Do Not Open. In 1958, Tennis for Two used an analog computer and an oscilloscope to turn simple physics into a playable tennis-like demonstration. A second detail makes the picture even better: Space Invaders, released in 1978, helped push video games into mainstream popular culture. Grombi files that under: small game, surprisingly large backstory.
