That's not in the epic game.
Yes it is. You can mod it in.
Most about this expansion looks exceptional! My only gripes are:
* We got privateers, but I still miss the coastal raiding pirates from Civ 1-2
* No new resources (I want seals, peat, tobacco and rubber back!)
* No new terrain improvements!
* No new animals (how about crocodiles, snakes, sharks and giant squids?)
* I also miss some military units (Dreadnought, biplane, Super Battleship, Super Carrier)
* More naval/air promotions (Torpedo, Carpet Bomber, ASW, AA)
