Those are new. Neat.
A National wonder, the Moai statues allow you to pull some production out of the water in addition to food and commerce. They're also good for shooting down any starships that happen to fly by.
Great Spies are new to the espionage changes in this expansion, so not sure how to proceed here. Great Spies can join a city to increase its espionage and income, or they can build Scotland Yard to double the espionage output of a city. Like a Great Scientist and its Academy, it's almost always better to build the building in a new city than slightly increase the espionage output of any city.
Mass Transit systems are new, and increase the health of cities that have them (by avoiding pollution, so technically they should decrease sickness, but
).
State Property negates city upkeep penalties for cities being far away from your capital, which is great for almost any size empire. But in this expansion it also negates the effects of corporations, which I haven't had a chance to experiment with yet.
I'm pretty sure no amount of aid will negate Montezuma thinking of us as his worst enemy, so fuck 'em.
My counterintelligence has caught several spies roaming through my lands already, but this is the first time they're able to actually wreck something. To be fair, I was going to replace that Workshop anyway (it was near Seville and I haven't finished remodeling the landscape around my newly-conquered previously-Spanish lands yet), but I am going to give Montezuma
such a pinch.
Shortly after that, two towns and a mine are caught in a volcanic eruption.
Keeping on good terms with your vassal states keeps them your vassal states.
The Great General I got for free by discovering Fascism pulls aside a Rifleman and gives him one hell of an intense boot camp of training, for +20 experience points.
Look at all those promotions! And with a Warlord leading them, these guys will always promote into the next available unit upgrade for free. In this case, they upgrade from Civil-War-era Riflemen to WW1 Infantry.
I hope to squish you by the end of this game, so I'll pass.
Where do you get Uranium? I don't have an Anium.
Treasures, texts, and artifacts from who? I'm the only one who's ever settled this land. And how are they teaching us how to
fly?
Biology is kind of a pain to discover, since I carefully plan out how much food each city gets, and the extra bonus from every farm means I often have to replan it all.
It also unlocks a National Park, which negates health concerns from overcrowding.
They're woefully underdeveloped but I take them anyway, giving them a build queue that will probably last until the end of the game.
Corporations are founded by Great People, so now that I have one (that isn't General or Spy) I start poking around to see what I can do with him. I found Creative Constructions in Poverty Point. I think that consumes the nearby Marble, making it unavailable to the nation as a whole, but all the stuff that is quickly built with Marble is done already.
Windmills and Watermills generate extra money, and I can build Broadway.
