Is the game of Governor true to historical facts? In many cases no.
Governor is a computer game for entertainment, not a history book. For example,
the geographic extension of the Roman Empire in this game is based on the Roman
provinces as well as the client kingdoms and dependent tribes that were parts
of the Roman sphere of influence sometime between ca 300 BCE to 395 CE.
The other differences between
the game and the historical facts are too many to mention here, just remember
to have a good time when you play the game!
