A strange little side quest
There is a neat bit of history hiding behind the kind of play you find in Conquer Antartica. Games resembling checkers were being played thousands of years ago; evidence of related games reaches back to around 1600 BC. The timeline takes another interesting turn: Doom changed game design and distribution in 1993 by separating its engine from content and spreading widely through shareware. That gives Conquer Antartica a little more company than it first appears to have.
