A strange little side quest
The fun part of looking behind Hall of Palletes is seeing how many older ideas are still alive in modern play. Arthur Wynne published a diamond-shaped 'Word-Cross' in the New York World on December 21, 1913; the name later shifted to 'Cross-Word' and then 'crossword'. It also connects to a different milestone: Atari's Gran Trak 10 from 1974 is recognized as the first arcade racing video game. Not bad for a few facts hiding behind a Play button.
