I have just started my first Medieval campaign as Egypt seeing asthough it said they were easy to play :). early days yet, nothing has much has happened. I have secured an alliance with the turks, not sure how reliable that will be (I may be too used to Rome)

I have built ports, farming and keeps in as much provinces as I can And I am building up a military. Should my firt moves be to the Byzantines or across africa? Will the Turks help against the Byzantines?
