Whenever I'm trying to play from 4000 BCE on an Earth map, Egypt and India are extremely overpowered. Egypt usually gets the Printing Press by the dawn of 1000 CE and in one game discovered: Buddhism, Judaism, Confucianism, Christianity and Islam! Also Egypt owns pretty much all of Africa! And India keeps owning all of Indonesia, Australia and invades China and Iran. And in one game they discovered Hinduism, Judaism, Taoism and Christianity. It's so frustrating, why are they so powerful? Other Civilisations just keep getting dominated! And England and Greece are always the weakest ones, staying in the Classical era until about 1500 CE!
