The first thing you want to do is take all your good troops in alexandria, memphis and thebes and build and army to take petra, bostra, and palmyra in quick succession. The numidians are very passive they will never betray u. Once you take one over, enslave them and build 1-2 peasant units, then keep going. Don't worry because they are all rebel towns Also build a diplomat in jerusalem and send it to dumatha(long way) to obtain trade rights and alliance from parthia. Do this with the numidians in lybia with the diplomat that is provided for you. Never, EVER trust the seleucids they are treacherous bastards and their word means nothing!!
If you want you can now take a break and build up your cities, for a couple of years. Then you'll either decide to attack the seleucids or you'll be attacked by them!!

First take damascus, if you want you can slaughter/massacre the population to free up your army from garrison duty, this is a highly mobile war! Then head for antioch, divide and conquer baby!! Their settlements are now separated from each other. Build a good garrison in antioch and head either west or east to rampage through the seleucid lands. Missile troops are very good against their phalanx troops, just sit there with your archers and soften them up. After awhile throw in you chariots break their lines and send in your infantry to slaugther the rest. I suggest you don't fight parthia, they have their cities very far in the middle of the desert, and it takes awhile to get you troops there. Just go for the greek city states and pontius.


The rest, well thats up to you..
P.S. Don't use numidian spearmen, or any desert infantry on hoplites. They wont even hold for a second. Use chariots, and missle troops. Infantry is afraid of chariots..
