Oh man, that sig is disturbing xD
The problem I see with adapting the system of lords into tpw is that each city state would have a different definition of "elite". One way of getting past this is merely labelling the lords as "generals", but that still leaves the question of political marriages and how they would be handled in ancient greece. I guess with the exception of Sparta, most commanders from the various city states would either be members of the aristocracy, or wealthy individuals called into military service.
Also, I like the idea of a scythian warrior- woman companion, although this means we'd need female versions of some of the armour meshes...
I vaguely remember silver mines being fought over a lot during the war, so you could add a number of villages marked as 'mining colonies' or somesuch- these would have a separate set of upgrades and would not provide any recruits, but would generate a much larger amount of money in taxes.
