A strange little side quest
If Dead Void sends you down a curiosity rabbit hole, start here. Doom changed game design and distribution in 1993 by separating its engine from content and spreading widely through shareware. There is another connection worth keeping in the same mental pocket: In 1958, Tennis for Two used an analog computer and an oscilloscope to turn simple physics into a playable tennis-like demonstration. That history is one reason familiar mechanics can still feel new when they are recombined well.
