One thing that always bothered me about the Civ games was they left important things out of the game, which you can not ignore.

Slavery. This has been a huge subject through the civilized time of man, but was always missing from the games. But the designers have realized that you can’t ignore the fact the slaves made a lot of the greatest achievements that man has made.

Fascism. This is a very touchy subject but again the designers put it in and rightly so. Because at one time Fascism threatened the very existence of our modern society.

And last, a subject that should have been there from the very first Civ games. Religion. The fact that every great Civ has had some form of religion made it ridiculous that there was no religion in the game. But thankfully the designers have at last added it. And makes the game a more authentic history of man.
