Thanks for opening this thread

I'll keep this very brief; I haven’t got much time just now and I’m pretty exhausted to boot, and therefore probably not too coherent. This is both research for the beginner's guide and an attempt to satisfy my own curiosity.

In 1.1 roads and trade worked like this:

  • The first level of roads adds nothing to land trade.
  • Paved roads always doubles land trade,
  • Highway increases it by a further 50%


So if you have a land trade route worth 100 Denarii with no roads, with will be worth:
Code:
Dirt	Roads	Paved	High
100	100	200	300
I want to know if this is still true in 1.2. I'm dyslexic and the kind of maths that gets these results is beyond me, so I'm asking for help. Actually about all I can do is take the results and copy them to the beginner's guide with credit given :embarrassed:



Part 2 of this topic deals with roads and movement for units and armies. I want to know how much of a boost each road type gives, and if all units receive the same boost. I suspect all army unit types (infantry, cavalry, artillery) will gain the same, and I expect agents will gain the same boosts as armies but you never know. Cavalry, for instance, has a larger base movement stat than artillery and if roads if a percentage based bonus then cavalry will gain more from them than slower units.

This part I can and will be working on myself, although quite how I am going to research it I have not yet decided. The campaign map does not obviously display its squares, so measuring is going to be tough.
