A strange little side quest
The mechanics around Yuyu Hakusho Wars have roots that stretch far beyond modern browsers. Boxing entered the modern Olympic Games in 1904 at St. Louis. And then there is this: In 1958, Tennis for Two used an analog computer and an oscilloscope to turn simple physics into a playable tennis-like demonstration. That is the kind of background detail that makes another attempt at Yuyu Hakusho Wars feel a bit more connected to the history of play.
