It's funny, how different people play. My current AS campaign includes leaving Anatolia and Egypt to itself and blitzing Central Asia. I've moved the capitol to Susa and I'm wiping out Parthians, Baktrians and even making fair border cities out of Chach and Alexandria-Eschate. My plan is to let Hayasdan and Pontus grow in force so they can be a challenge later on. Also, I'm turning history upside down. Instead of ignoring the east as the real Seleucids did, I'll ignore the west and see where it leads me. Once Baktria and Parthia are gone and India has been invaded, you have an unstoppable machine in your hands :) (by the way, it's fun to fight Parthians with a full-stack of Phalangitai - since they cant shoot you, they have to charge you and sometimes they even succeeed in splitting you up and defeating you. other times, theyre wiped out)
