If civ was real life.

If Civ was real life, every archaeological site looks like Stonehenge. You tear down the stone circle to get to the coin underneath. Tourists flock to see the coin, rather than visiting any intact stone circles.

If civ was real life, a bunch of cavemen with clubs could capture a modern city, if that city had been reduced to 1 hp. The city's missiles would kill 9 out of 10 of the cavemen, but the tenth one would be able to capture the city somehow.
