Aye, in late... the Romans are in rough scattered shape. Ive always found it takes at least 30 turns to really get a solid hold on Greece and west Turkey.
Usually, by turn 50ish, Im sending one strong army into eastern Turkey and one into southern Italy, starting with Sicily.
The best start Ive had... I had all of Turkey, Greece (with the Sofia boundry) and Italy by turn 85ish and was ready to send strong armies into the holy lands and N.Africa.
By turn 200, I had recreated the Empire (at its height)... minus Genoa, northern France, England and that tiny island east of Spain (thats where I kept the Pope sequestered
But, Genoa and Papal States were my vassals so...
Havent played that save in a couple months but, the darn French-Brits are the monkey in my wrench so far.
