This might not work, but the easiest thing to try is to go into the "...\Rome - Total War\EB\Data" folder and rename the descr_cultures.txt. Then go into the "...\Rome - Total War\data\" folder and copy the descr_cultures.txt and copy it to the "...\Rome - Total War\EB\Data" folder. That should make all of the strat map models the vanilla version without having to alter the files line by line. (If it causes a crash, just delete the copied file and restore the renamed one.)

Promethius, who made the Greek and Roman towns quit modding before the Eastern models were made (I think he may have lost his half finished ones). I tried creating eastern walls once (with similar shapes to Prom's), just so that the cities aren't square, but couldn't figure out the final process of saving the file and nobody could help me.
