Siberia will never generate a great person unless there is an emergency. Why dont you just work 4 GEs starting now so that you can work the deer and grow sooner?
I dont think Cuba needs a factory. With Mining Inc. it will have a max of 24 hammers. Im not sure it will ever pay off the 250 hammers it takes to build it...
Id build a coal plant before an aqueduct in Bermuda. It will pay for itself very quickly.
Rheims should build a factory/coal plant after the executive.
Where is the Bananas settler going? Why build a partial factory and then galleon/settler? It seems to make more sense to either finish the factory or just skip it for now.
If we dont need the forts near Paris, we could workshop them.
Orleans should stop working the bananas and farms to avoid more

. A fort could be changed into a workshop as well.
Guangzhou may as well build a coal plant after the factory, but this will be after your next 4-5 turns.
Build a coal plant after the factory before wealth. A quick library would be good. It could also build an MIE for Nanjing. Since this is hammer city, Id change that windmill to a mine, steal the workshop from Nanjing and convert the plains farm to a workshop.
In cities like Haiti, Id run merchants rather than scientists. It only has a library, so the science multipliers are small. Running merchants just about everywhere we are not trying for a great person will allow us to inch up the slider, which converts more commerce to beakers in our developed cities that do have all of the science multipliers.
Should Hastings at least finish the forge first? It should pay for itself quickly since it is nearly done.
