Well for a start with GLH it is easy to keep the economy going. For another 7 cities normally means a good number of unique resources; these can push up happy and health caps letting your work more tiles in your core (and perhaps get more gold in trade from higher pop sizes). Then let's remember that there is plenty of commerce to be had at astro - dye, spice, gems, Au, Ag, marble. Even if you just get a few more horses and cows you can normally sell those for some pretty nice gold.
As far as production umm there is this civic called OR that gives you more

, there is resource called Marble which gives you yet more

and there is this mechanism called
chopping which gives you 30 base

. You can easily get half the

out of chopping and it really doesn't take that long to get good production up. At this point you can ship over idle workers and quick build a lot of improvements. Give me two wet corns and this place will be a production powerhouse in no time at all.
I did see someone do something like this with a Great Engineer on a Prince game...and that's cool and everything, for Prince.
Well it is among the best uses of a GE for certain setups outside of founding a corporation. If I have a strong GE pump lined up (future IWs cap with the mids, HG, HSophia) I will ship out a GE to make insta-verseille as that is FAR more profitable in the mid and long terms than a GM mission. I've done it twice on deity (IND with stone)
OK. I could see that. I suppose my fractal ways did influence much of what I said.
So the player wants to avoid economics but get 3GD and then complain if it's not in the perfect spot? Cueing the worlds tiniest violin
Oh please, take any late game war mongering strat you like that doesn't beeline industrialism (e.g. the massively overpowered flight option). On higher difficulties you can either gun plastics and build 3GD or you can gun other options and let an AI build it. There a
massive number of viable strats where you don't get coal plants everywhere before 3GD becomes viable, particularly if you are having health issues (like say when SB is next door and is someone's vassal you can't yet afford to attack)
You don't have open borders with or plan on taking over the tank AI? Seems like you might lose that city.
If you're building

from scratch next to a legendary city, you'ld be screwed even if Broadway kept it's +50%

when taken over.
Huh? You have a large stack with snaps back into the city. With enough garrison the place will never revolt and your are good to keep it forever. More often the trouble is your stack is now stranded. The real problem is the city not being connected to your trade network.
So then you agree with me.
No, you are completely missing the point of the thread. The point is to delineate when this is an assymetric opportunity cost of acquisition vs building. Just because you can afford to build GLH, doesn't make it a good option. Instead you should look at the opportunity cost of building the GLH (what could you do with the

instead), and what are the odds that it will be built by an AI near you (this can actually get quite high if you have two wonder whores next door who have resources needing fishing and masonry). What this thread is looking at is when do you need to discount the value of capture, after you have made the trivially obvious step of discounting the chances that it will be built far away. The try to build it vs try to capture it comparison requires a component considering the assymetry of some wonders; this in turns effects the calculation of cost effectiveness for building a huge pile of axes or trying to build a wonder.
Why you persist in reiterating a trivially irrelevant point is beyond me.
