I find it curious the way some parts of the world are represented by tribes that really were around when the game starts, and others by modern nations. Thus there is Australia (modern) but no New Zealand (represented by Maori - ancient). In Latin America we have the Aztecs, the Incas and Mapuche, but no Mexico, Peru or Chile, yet we do have Brazil. There's always something slightly weird about Canadian spearmen and Maori battleships! Which is the most unsettling anachronism?
