My point is that culture doesn't change that much in 200 years.
Unless you wipe out the town... still, people in the surrounding countryside retains their former culture.
Megas Alexandros started his campaign in 336 BCE and he died in 323 BCE. The game time starts at 272 BCE and this means 50-60 years after the Alexander's conquests. Some of the provinces of Alexander's successors are homeland regions of them and this means in 60 years the culture of people in Middle East or Egypt changed to Hellen according to the game, so culture can easily be changed in 200 years.
