A strange little side quest
One reason action games keeps producing good game ideas around Head Hunter Reborn is that its history is full of strange turns. Doom changed game design and distribution in 1993 by separating its engine from content and spreading widely through shareware. The broader history adds one more wrinkle. Spacewar! appeared on MIT's PDP-1 in 1962 and became one of the earliest influential computer games shared among programmers. That history is one reason familiar mechanics can still feel new when they are recombined well.
