A strange little side quest
One reason combat sports keeps producing good game ideas around Gatka Grid is that its history is full of strange turns. Boxing entered the modern Olympic Games in 1904 at St. Louis. Another piece of context lands nicely beside it: Games resembling checkers were being played thousands of years ago; evidence of related games reaches back to around 1600 BC. That gives Gatka Grid a little more company than it first appears to have.
