A strange little side quest
A small trivia drop for Keyboard Heroes: By 1987, fantasy role-playing had become a major computer-game direction, with Zelda, licensed Dungeons & Dragons games and other story-led adventures expanding the form. That old idea kept changing rather than disappearing. In 1958, Tennis for Two used an analog computer and an oscilloscope to turn simple physics into a playable tennis-like demonstration. Grombi files that under: small game, surprisingly large backstory.
