600G last time I checked for a court house, but the challenges that I am having is :
Taking cities is...
a) dangerous if you do it without ranged units
b) slow if you do it with ranged units
Once you start taking cities...
a) happiness is an issue because you can no longer create large happiness buffers
b) and razing cities will create a lot of unhappiness anyways
Playing defensively...
a) puts you behind since the AI techs at an incredible rate
b) they will nuke your defensive lines constantly (normally around 1600s)
So either way you can't just march and keep marching. Which is an issue because its seems that its hard to keep on even ground of tech.
On the plus side, I've been looking at other options to help keep me in this game which basically involves me trying to each AI to start wars with each other and see who will do it for the cheapest, since I don't really care who starts it.
I think everything is for the better, I mean Immortal is supposed to be hard and not a cake walk which is way previously.
