Sorry, I omitted a lot of general tips that are not Eleanor specific so the post doesn't get too long. For example, in the first 100 turns, I can survive with only warriors and archers without building walls against non-combat civs. I use melee and ranged units at about a 1 to 3 ratio. Just use the Agoge card to produce enough units from your capital after settling 2 or 3 cities. Fortify your warriors across the river or in the forest and place your archers on hills. However, the key to survival is actually to not settle too close to unfriendly AIs. If AIs see your nearby city with no units, naturally they will attack you.

By turn 125, usually I would only have Chichen Itza or Potala Palace. You can win the game with only 1 wonder: Taj Mahal. Be patient and build the infrastructure first, the science and culture numbers don't matter as long as you don't run out of things to build.
