It feels weird that you cannot win this game outright before the third age. From the perspective of a time period person, I'd say Alexander won (domination), the Romans won (domination/cultural), Arabia won (cultural, scientific, domination), Genghis won (domination), Spain won (domination, religious), France won (cultural, domination), England won (economic/domination), etc. In a game where everyone is in the game at 4000 BC(E), and has equal ability, why shouldn't the game stop at the first player to win (Alexander)?
