I liked the other map more
Here the opponents are closer, we are at a coast leaving only one direction to expand and there are less Health/Happy ressources in the vicinity.
I think you need to settle
really boldly here. Meaning sending your settlers past your neigbours, to grab important city sites and ressources. I would concider trying to box in Pacal completely.
The maintenance will go up fast - well it's not like you really care about research in that game
Try settle one riveside city - maybe those cows/floodplain SW from capital and cottage it up, so it helps pay for your settled cities maintenance, then settle untill the economy really can not take any more abuse.
Try take CoL from Oracle. The Cotrthosues will start giving your Espionage points and help recover from the early Rex-rush.
Just don't put the oracle in the same City with the Great Wall - you dont want to polute the Spy GP's. The great wall will be doen faster, and running GW+Spy for Courthouse, the oracle will never pop a prophet. Maybe Chop oracle in a city at pacals border, to make some presuure on him.
