Extensive look through?
1)Condate, why are we farming the wrong tile to Irrigate the Corn to the NE. Denoted as a hammer city, Plains should be work shops, grassland farms, Hills all mines, No cottages at all.
2)Pons Aelius, Culture, long hard battle to take any tiles, but must do something.
3)
Madrid (ours and holy city) Toledo (Cathy non holy) Both have been reset Culturally to Zero, NOW is the time to take tiles, best and only opportunity, CULTURE IN MADRID, CULTURE CULTURE CULTURE. That and gold Multiplying buildings. Wall Street Needs to be built here, along with the 2 corporations that we'll found. Sids Sushi, for the Culture aspect as well as food, and mining Inc, for the hammers.
4)South of Evertonium, we'll need to settle a city, it'll be taken other wise. Complete Cultural blockade to the Eastern Entry there as well, Catherine has settled the dual Oil Further East.
5)Neapolis, should get West point built there, 15 Exp troops then.
6)SW of Circei, we need to build a Cultural blocade on land throught there, settle a 1 tile island to block off from West entry.
7)I'll probably decide on other cities as I play, but Commerce Cottages on Grassland, farms for growth. Production, only mines on hills, Workshops on Plains, Farms on Grassland.
On diplomacy;
NEVER EVER TRADE WITH GANDHI. Our optimum opponent would be William. How do we do this??
a) We go to war against Gandhi, take his cities, and gift them to William.
b) We gift resources, food etc to William.e Don't go overboard about defending him, but plump him up.We have to build the United Nations, or get William too, build in a city and gift it to him?? breaches rules, No.
c)Hammurabi and Alexander, Catherine's Vassal, are Mutual Worst Enemies, Potential for future conflict there possibly, but wouldn't hold out much hope.
ci)Settle more cities if only for resources,and land potential. Deny to Ai, but gift other to William.
Switching of Civics. I don't see the need for it, stay in Hinduism, we're getting +7 and +3 from 2 Hindu's now, go back to Organised religion is the only swap I'd advocate. We don't want a friendly William he's our Opponent.
Switch Catherine back to Hinduism, using Espionage and bribes, and spamming Hindu Missionaries to non Hindu cities. She's a Possible Cultural Victor, or switching to Islam totally.
Government; Representation, for the Specialists, switch to Hereditary rule for Vote. Use Christo Redentor.
Legal; Bureaucracy, a definite, for Rome. No switch.
Labour; Caste System for +1 Hammers, or Slavery?? Possibly Emancipation later on.
Economy; Mercantilism and SoL gives +2 Specialists. Free market more trade routes, but if big enough, internal would be enough, state property, +10%

Religion; Stay in Theocracy till Christo Rendentor, then Organised religion. Stay a Hindu.
To sum up;
Build more settlers,
Run Science at 70%, quicker then building up cash for 100% run. With forbidden Palace coming online, saving more cash.
Flip Toledo, Culturally, if Catherine gifts it back to Isabella, we're in Deep DooDoo.
Don't get involved in a Catherine V's Hammurabi war, if it ever happens.
Mines over windmills in production, only in commerce cities.
Long term;
War with Gandhi, gift cities to William.
South, Settle out lands
East, Settle and gift to William.
Resources, settle cities to Gather.
Stay Hindu.
No civics switching till Christo Rendentor is built.
