Remember in Civilization, eventually you build up enough technology and knowledge, and your civilization develops into modern times? Pavement is discovered and integrated, gone are straw huts and mud homes, in place of actual buildings and skyscrapers. And you get to witness all this advancement throughout game play, and you feel this sense of accomplishment and talent at deftly building your society, and advancing them through the times.
But in the blink of an eye, another country comes in and invades your towns and cities. If you cannot defend yourself from them, they will take over your properties. And in doing such, often times, they will steal your technology and knowledge, but in some cases, they’re more or less comparable primates, and they take your land back a few eons of development.
Take note of how New York City looks – before China invades and takes over the world.
