There is a neat bit of history hiding behind the kind of play you find in Rush Royale: Tower Defense TD. Games resembling checkers were being played thousands of years ago; evidence of related games reaches back to around 1600 BC. That is only half the story. Atari's Gran Trak 10 from 1974 is recognized as the first arcade racing video game. It is a good reminder that simple game mechanics can carry a surprising amount of history.
