And a general point about isolation...
There seem to be some sort of consensus that it's best to hold of expanding beyond 5-7 cities.
I have a hard time internalizing this wisdom since I don't quite understand the reasoning, do help me out!
There are basically two types of isolation, one where you have enough land to keep your calm. You can develop your empire and look for an edge to leverage upon much later. The other type being that you are cramped for space and need to hit someone early.
In the case where you are in a rush, I do see the point of getting to astro as early as possible, and then it's worth to put a break on expanding.
But when we are not in that rush, why are we holding back our expansion?
The only key techs that I can see that we need to get is pottery/writing, and for certain all limits are of by the time we have currency, no?
Using
@sampsa 's rough guieline of "the 4th city cost me 4gold, the 5th cost me 5gold, etc".
What is the point of settling city 8 at T150 instead of T100?
If it takes city #8 20 turns to start contibuting 8 gold equivalents to the empire, thereby carrying it's own weight and after that contributing...
Why don't we want this positive contribution at T120? Why do we want to wait untill T170 to get this?
Is it that you are seeing astro and overseas forregin trade as another bottleneck that we want to get through even with the calm developing aproach, such that 8+ cities isn't really working out for us?
What am I missing here?
