Once the game has started:
Change your government to Monarchy to start. Defend with your 1st Modern Infantry. Barbarians will most likely attack you, which in time is good for you, as it’ll upgrade your unit making them better defenders. Go into the city screen and immediately press , this will switch your city from producing science, (which you don’t need because you have all technologies), and you’ll start producing gold. Next go to customize your workers, putting some on food, some on tech, and some on gold. Then change what you are building to a temple. Once you’ve built the Temple, build the Cathedral.
At this point you should get your first Great Person, or will be close to getting them. You should settle any Great Person, unless it’s a Great Builder. In which case you should use the Great person to complete a wonder for you. Magna Carta should be the first wonder you build.
Next you should build a Courthouse, then a Market, then a Bank.
Once you have 100 gold and you earn your settler, use that settler to build a new city. In this city you should go in the same order building a Temple, Cathedral, Courthouse, Market, then a Bank. You should also immediately change from science to gold. Also remember, if you can’t settle a Great Person in your capital, move the Great Person to your second city and settle them there.
Never use a Great Person other then to settle them, unless you can use that Great Person to complete a Wonder, or if you can use that Great Person to Culture Flip a city. If you get a Great Person that you can’t settle in your first 2 cities, hold on to them and build a 3rd city or take over a city and settle them in the next city.
At this point you should build 2 more modern infantry for each city, and combine them to make an army, and you should build 1 Artillery unit that will help defend the city. Build a road between each city. Once other civilizations start bothering you, defend with the modern infantry but use your Artillery to fight the enemies Artillery.
Once you have those defensive units in place, you can start building wonders. Start building Wonders from the lowest amount up to the highest. If you get a Great Builder in the middle of a Wonder, hold on to them and use them to build one of the higher cost Wonders. Also in between Wonders, use your gold to build a building before you start the next Wonder. Like a Factory, Iron Mine, or some other building to help you raise your production. Make sure that you build the Manhattan Project and not another Civilization.
You’ll come to a point where eventually you’ll have to take over a city or 2. This will allow you to build more culture, and in so doing will allow you to flip cities using your culture.
Tip: You can only flip cities if you know they are there. You could be just a few moves away, but if it's under the war fog, then you can’t flip it.
The best way to take over cities, are to mass produce Bombers, form some wings, and have them do all the attacking of cities. Then once they are sufficiently whittled down, move in some ground forces to take it over.
Once you’ve taken over a city, the first thing you want to do is build a temple, buy it, and then start building a Cathedral. Then next round you’ll buy the Cathedral and start building a Courthouse. Next round buy the Courthouse and what you build after that is up to you, though Harbors, Granaries, and Aqueducts are a good way to go, (Because the bigger your city, the more culture you earn) By doing this you are increasing your Culture and chances are you’ll start converting cities over with your culture. Also, don’t forget to build roads connecting every city that you’ve taken over.
Feel free to take over capitals, since palaces give you more culture…just don’t take over ALL capitals. You shouldn’t need to flip too many cities, as Wonders built and Great People settled should account for about 14+ out of the 20 needed to be able to build the United Nations.
