Maybe you could do a combined AAR and lifestyle guide - there is enough geographical info from Strabo for you to be able to give the reader detailed advice regarding the holiday home and buy-to-let potential of each settlement you capture.
We will also expect full coverage of the Olympics (including drugs scandals).
If you fancy house rules, then here are some suggestions...
Don't exterminate - Greek society values robustly opposing views. Rebellions are just an opportunity to demonstrate Greek manliness and martial prowess again (and again, and again).
If you find the Greek War Machine is becoming too effective, then try role playing your generals according to their ethnicity (Spartan, Athenian, Rhodian etc). You can practice the Ancient Greek tradition of not helping your neighbor.
Don't use those boring Iphikrates imitation phalangites. If overarm was good enough for Grandad, it should be good enough for you. And don't forget - real men don't fight on horseback!
If you find you have enough money to feel comfortable - buy some catapults and bankrupt your economy.
