Age of Chaos is about building your empire and getting the Royal Palace before anyone else does. It's therefore vitally important that you build your buildings fast, efficiently and in an order that serves you well.
Certain buildings give you certain extra benefits like extra professions for your people to enter, or extra food production and allow you to build bigger, more complex buildings. Deciding which ones to build in what order is key to success.
You need resources to build with (such as wood and stone) and so you need to have people making these things for you. How much you should make depends on how much you're going to need. Making way too much is a waste as resources always decay over time. Getting the balance right is part of your planning.
First you need to start building the construction yard. All other buildings require atleast a construction yard so this is always your first building. You then need to assign your peasants. You assign workers to a job by entering a number to assign in the field next to their name. You should start with about 30 farmers and some merchants, builders and woodsmen. Seer will allow you to view other lands but aren't useful until your out of protection. You should also hire one militiaman.
