Buildings Overview
The Buildings Overview allows you to see the current level of all buildings in your city. Any of the buildings that have an arrow next to it, can be interacted with. All you need to do is click/select that building, and it will take you to the corresponding overview.
Senate
The Senate overview allows you to view the current build queue and how much time remains until the completion of each building. Also, you can use this overview to build new buildings and upgrade existing ones as long as you have the resources to do so. You can see whether you have the necessary required resources underneath the building image. Resources in black means you have enough, but anything in red means that you are still short of that amount. Additionally, the time it will take to build the next level of the building will also be displayed.
In the build queue, you can cancel buildings, and also cut the build time in half using gold.
Barracks
In the overview for the Barracks, you will see the amount of troops that form that city's army. Underneath the images, you will see how many of that troop type you can train. By clicking on any of the images, you will see the unit stats, resource costs, and time to train.
As well as this information, you will also see the training queue, and how long it will take for the training to complete. Just as with the build queue, you can reduce the training time with gold. (If that world has that feature)
To train troops, just click on the type, and either train the default amount, or enter a new number and confirm by clicking Recruit.
Academy
To begin with, you need to make sure that you have built the Academy first before you can interact with this overview. Once you are able to, you will be able to see how many research points are available, and which technologies you have researched or are able to research.
Just like the Senate overview, those resources shown in black means that you have sufficient of that type to start the research. Any resources in red, means insufficient resources. Technology that you have already researched will show a green tick mark in the image and the image will be in color.
You will also be able to see the research queue, and should you wish to, you can accelerate the research by using gold.
Harbor
The Harbor overview lets players construct ships while on the go. The overview displays the size of that city's naval forces, and how many ships of each type that can be built. The stats of each vessel are also shown, as are the resource costs and the time to build.
In the training queue, you can see how long it will take for the ships to be built and also reduce this by using gold.
Temple
The Temple is where you can get all the information about the god that your city worships and how much favor it has with that god. Each god's favor is represented with a different symbol so that you can distinguish it from the others.
As well as the information about the patron god of the selected city, you can also see which spells from the other gods can be cast and what mythological units they provide. You can also change which god your city worships through this overview as well. For more information about the gods, see the relevant Wiki page.
Cave
In the Cave overview, you will be able to add silver to your cave to enable your spies to do their job and both gather intel on other cities and prevent espionage on your cities by other players.
You will need to deposit at least 1000 silver for your spy to conduct missions, or to be effective at counter-espionage. Silver that is put into the Cave, remains there until you use it for spying missions, or one or more players sends enough spies to your cities to deplete the silver already stored in your Caves.
Farm
As in all times of war, it will be necessary to defend your empire through all means possible. In the Farm overview, you can activate the militia to assist in defending your city. Of course, while the Militia are active, your resource production drops by 50% over the 3 hours that the people are on duty defending the city.
Each level of the farm brings 10 militia (15 militia with City Guard researched). The maximum militia that can be enlisted is 400 militia (600 with City Guard), or if you are playing in a Hero World the maximum is 450 militia (675 with City Guard).
Agora
When you go to the Agora, the overview will display your current cultural level, number of city slots, and how many Culture Points you have. There are also two other views which can be seen on this overview: Culture Overview and Troop Overview
Culture Overview
In this overview you can increase your Culture Points by hosting City Festivals, staging the Olympic Games, holding a Victory Procession, or enacting Theatre plays. The costs of each event and its duration will be shown alongside the event.
Troop Overview
You can see what troops you currently have stationed both at home and abroad. Troops stationed in your city will be shown in three ways: All Troops, Own Troops, and Troops From X. Troops stationed abroad will be split based on the city they are supporting. You can choose at any time to send home any support your cities are getting, or recall all or some of your troops from abroad.
Marketplace
The Marketplace overview shows your city's current trade capacity and all trading activities.
