A strange little side quest
A small trivia drop for Don't Get Killed: 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: Midway's Gun Fight from 1975 was the first arcade video game to use a microprocessor. That history is one reason familiar mechanics can still feel new when they are recombined well.
