I am reading through your pregame setup. Does each terrain type only cost one TP? Do I purchase roads and stuff for each terrain? Can I have multiple unpaved roads for each terrain? What is the advantage of having roads and railroads in a terrain?
I thought you had purchased some terrain all ready, my bad, sorry about that.
Yup, each terrain type only costs 1 TP. Yes, you purchase the infrastructure for each region you wish to use. I would suggest at least one Super Region for one Open (plains) one for Difficult (Forest) and one for Very Difficult (Mountains). And then one Very Difficult (Desert). Since these will give a boost to the various vital production you will need, Plains = Food, Forest = Resource Extraction, Mountain = Resource Extraction, Desert = Solar Energy Production.
The advantage is that without the transport net, nothing gets moved except at a snails pace. Think every Cargo Point is being moved by hand cart and wheelbarrel. Then there is the Wealth bonus to.
The Intro to the Transport Net Rules:
[6.4.8] Transportation Networks
One of the most important things you will need to understand is that without a transport network the raw materials will not get from the mines to the factories and the supplies to keep your war machine running will not move. So it is critical that you keep the idea of throughput in mind when planning your transport network. Throughput is simply the amount of cargo your transport network can carry over a given amount of time. For example of you have a road network with a throughput of 30,000 cargo a month, that is the absolute maximum it can handle. Any more than that and you begin to experience the bad side of a transport network, Logistics Jams. These are only a minor irritant in peacetime, but in times of war they can be downright deadly. So keep an eye on your transport network and you will be on your way to an efficient movement of goods and troops.
