On Noble setting. It seems that just when I get to the point where I can put out Archer sentries and begin building Swordsmen, there goes the money. My tech drops to 40% or so, and if I keep building swordsmen it goes all the way to nothing and my workers start getting killed off. I've seen my enemies and they often have more cities than me, and are more technologically advanced.
This usually comes between the time of IW and Currency. Usually my civics don't change at all, so there's low maintenance for everything.
