A strange little side quest
The rules may be simple on screen, but the backstory around Hero 2: Katana is anything but tiny. The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. And then there is this: Boxing entered the modern Olympic Games in 1904 at St. Louis. That is the kind of background detail that makes another attempt at Hero 2: Katana feel a bit more connected to the history of play.
