This seems like a hard Emperor level game. With no trading partners, the other AIs may be well advanced before we meet them. I hope any new players are either highly skilled or take the Adventurer save.
Settled 1E and beelined iron working. Then decided a Praet rush of Alex would be too costly, better to put my effort into my economy and let Alex build me some more cities = wait for catapults (then conquer whole mini continent).
So, focused on getting CS from Oracle and succeeded:
675BC: CoL, Oracle, CS Rome (3), Antium (3); 6 warriors, 3 praets, 2 workers
Tech: Agr, BW, IW, Wh, Pot, Writing, Myst, Med, PH, CoL, (CS), AH, Math, Constr, Hunting, Arch (1AD), [next monarchy]
1AD Cities: Rome (6) 1E; Antium (5) 1W of iron; Cumae (3) SW of wheat, E,SE of horses; Uzbek (2) 2E of copper, SE of grapes [captured from barbarians]
6 warriors, 7 praetorians (+1 next turn), 4 workers, starting to build catapults
built in a far away land: Stonehenge, Pyramids, Parthenon, Great Light House, Kashi V
Alex: 7 cities
lost two low odds battles initiated by barbs (4.4% axe on axe) otherwise my praets handled them
razed city (Burgundian) that would have kept me from using the fish, then barbs rebuilt it in same spot

(now with archers)
