A strange little side quest
The fun part of looking behind Happy Easter Rabbit is seeing how many older ideas are still alive in modern play. Doom changed game design and distribution in 1993 by separating its engine from content and spreading widely through shareware. The surprising part is how quickly the next milestone followed. 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.
