jatibi, thank you for the irrigation garphics, so you are right, they are somewhat too small.
I have updated the techtrees posting with the era 3 (industrial) techtree of that mod.
And here is some more eyecandy. Different resource cities that are captured by civs from other regions to test how walls from "strange" civs harmonize with the basic resource cities. In the testrun there is also varwnos´new serb city, that harmonizes well with the resource cities.
Thessaloniki is captured by the Chinese and has at time a Chinese wall around that city. Sofia is captured by the Germans and therefore at time with a northern European wall around that city. Istanbul has a mediterranean wall around it. Tirana, Odessa and Troj are occupied by the Romans and have a Roman wall around them. Bucharest is at time owned by the Carthages and has the mediterranean wall around it.
Please note, that the graphics of the walls chance when the city is captured by an other culture group and when there is no wall in the city there is no wall to see on the map too (here is at time a little problem with varwnos´ new serb city as it shows a wall even in the "no-wall-graphic").
I consider an open playtest of this mod, may be with a smaller download file than the normal file to cut download times as short as possible.
O.k., I reveal another secret of these resource cities. The screenshots at time show the normal civnames of the cities and the cities are owned by normal civs. But these cities all get names by additional resources.You must fight for every city against the true inhabitants of that city. These minor civs, most civers call them barbarians, can defend their cities well. Most of the cities contain barbarian camps that are set to transparency. If you want to have Troj, you must fight against the Trojans.
