I believe they must be on Magnetism and Metalurgy by now, they are just doing the same they did for Education and so on, they dont trade the techs between them until they know we and BABE have them, it´s kinda cat and mousse, they are pressuring us to gift the GLib to BABE now, in order us to get only 1 tech or 2 maximum, we have to be patient i think.
Making new cities will increase corruption and hinder the core ones productivity and our ability to make wonders/military.
We are only gifting GLib once they have Steam Power.
With Democracy, both us and BABE can railroad everything 150% faster then normal, dont forget we only have about 25 workers now, thats not too much, and there´s still a few jungle and mountains to be worked, plus we could set up a chop/forest factory on ice tiles over in the north for a nice 30/40 shields free cost production per turn with Democracy.
Sistine´s have been built, but there is always the option to go for JS Bach´s Cat if we develop the other techs, since we have the gifting to BABE on our pocket we can make the best of it for a while.
I dont know what the BABES are resarching, i can only hope its banking.
But more important, FREE as Astronomy, and as started to scout our land, we must position our troops along the south continet side to blockade a possible FREE surprise landing, with caravels, MDI´s, Horsemen and Musktmen avaiable in the world its only good sense to watch out for our shores asap.
