Of course balancing isn't done, that's why I provide feedback 
Gold is a big issue to me.
Early on, there's no point building a city because it can't produce gold.
So you are reduced to ONE option, NO choice: Explore and pop goody huts. I like huts, but having no choice is not fun.
Later on, I find myself conquering a few cities and suddenly I drop to negative gold. I built 4 cities, only built food, pop and gold improvements, have very few units, built caravans to establish trade routes within my cities and with my neighbour.
Still, I find myself with <0 gold for some reason, which I don't understand.
I don't think getting into negative gold should be allowed. I know credit exists IRL, but here, who's going to lend us money?
IF we get into negative gold, we should be warned.
We should get an explanation how we dropped there, right now there is none.
In the Kingdom report, I can read the income:
+16.6, spending = 16.6. But then Caravans/traders income does not appear, which means the figures shown there are false. I actually have positive income, and yet managed to get far into negatives. How is it possible? It should not.
Also, 'Admin Cost' is not explained. I'm pretty sure it's linked to the number of cities or something like that, but it's not explained anywhere.
Worse, cities can't be disbanded or razed. I mean, I just conquered a city of Fallen, I might want to rase it to the ground, but I don't have the option.
In general, the Kingodm Report window should be changed by providing contextual info and explanations when you hover/right-click/click/select/pick your preferred interaction on information.
Wages are also weird. All my units cost 0.2 wage, be it a peasant (cost 3) or an armoured axeman (cost 55).
