A strange little side quest
The rules may be simple on screen, but the backstory around Rage is anything but tiny. Boxing was part of the ancient Olympic Games by 688 BC, long before gloves, weight classes, or timed rounds existed in anything like their modern form. A second detail makes the picture even better: 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.
