After a while of playing RTW mods you have an idea of what should be built.
For economy build and upgrade;
Roads, markets, ports (if you are on the sea) and get trade with your neighbours
This is a bit simplistic given the number of building options that you have.
In order to keep a growing populationhappy make sure that you build sewers and temples. The idea is to attempt to reduce the effects of squalor. Having upgraded sewers makes it less likely that plague will break out but will reduce the length that the plague takes effect. An AI spy with the plague may always infiltrate your settlement - I've used a similaer tactic with a number of spies and the chaos it casues the AI faction will cause them problems.
I will try and concentrate army production in the capital for Pergamon. In order to have the population to sustain arrmy growth you also need to look a tthe buildings that will boost population growth. In RSII there are even buildings specifically for this.
