I've looked at the save and have a few comments:
City suggestions (Note: I only looked at the city screens, so some workers might already be doing the tasks I'm suggesting):
London: Build and work some more cottages
York: Build and work more grass cottages
Corinth: Future missionary farm?
Thebes: Keep the farm on the floodplain to irrigate the city and therefore the wheat. Cottage everything else
Athens: Work food, keep scientists, build missionaries
Sparta: Future missionary pump
Carthage: Work food, make cottages
Timbuktu: More cottages
Kumbi: good
Gao: Make cottages
Let's hold off on taking the barb cities for now. We're at around 15% science with almost all courthouses installed.
I suggest we spread Christianity since we already have 4 cities with it (Hindu has 3). Also, we already have a Christian monastery in Athens. Don't switch to it until cities have popped borders though. Maybe another religion will spread to the cities without one and serve to pop borders.
I didn't think the Stonehenge-monuments expired with Calendar! That must be new with the patch. I suggest missionaries to pop borders.
I'm really at a loss for the tech route. I guess I'd aim for the ability to bulb Optics, but that seems so far away at this point. We need to work cottages. I'd only whip buildings to get rid of unhappy people.
Where the heck is Hannibal?!
One last thing: Not now, but down the road, we may want to build a panama canal, depending on where the AI is:
We'll have to see though.
We can always put workshops over the cottages in the future if we need to, but I'm thinking we're going to need Astronomy for this one. How about assigning 2 scientists in Carthage to help bulb it. The won't complete their work for 75T, but we may still need the GS.
And don't forget to switch to HR. The sooner the better.
