Here is my attempt at the mighty Roman Empire, Monarch difficulty v1.187. Had luck with early death of India so I could easily Oracle construction, and complete the Great Wall in the B.C's. Spent too much time building unneeded wonders like the Colossus, but I suppose these did keep my Empire alive later on.
Here's my Empire at 200AD, Trajan kinda time. I have only just finished conquering Carthage and Egypt, ended up turtling in the beginning after conquering Greece and Asia Minor because I am too trained to build good wonders. Still, I think I have control over most of the Roman Empire at that point.
At 470AD
And here it is in 600AD, with Ethiopia as my vassals. I could have gone made and built a hundred settlers in those 400 years, but I tried to stay historical, expanding where the RL Romans did. However I did just beat Persia! I think I ended up with 30+ cities.
By this time the economy had headed pretty downwards, and I needed to make money to keep it going even at 0% science. The stability was looking pretty scary too.
Now as it was getting towards the Arabic spawn I moved all my troops out of Jerusalem and Arabia Magna (1N of Mecca). However when the Arabs spawned I refused the flip and they all got catapulted to Persia, and took Shush as their capital! Because I refused the flip they even got more troops in Arabia. Luckily my armies were still mopping up Persia and all the City Attack*3 Legions quickly crushed all the Arabic defenders and they were destroyed!
