A strange little side quest
The fun part of looking behind Castle Chess is seeing how many older ideas are still alive in modern play. 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. Nintendo's Donkey Kong arrived in 1981 and introduced the character first known as Jumpman, who later became Mario. Grombi files that under: small game, surprisingly large backstory.
