The Fall of the Eleventh
It is a decent wonder. Perhaps a little situational, but then most wonders are. Rest assured in every situation it's better than Chichen Itza, the Hagia Sophia and the Space Elevator
Hagia Sophia is 550 hammers. A worker is 60.
So, if you get the equivalent of 10 workers value from the HS, it's worth it - it's 50% less time, so theoretically, you need half the workers. If you have stone, of course, it's 5 workers.
So I'd say that the value of the HS is higher on larger maps where you need more workers anyway. Or for it's GE points.
Value versus extra workers is true in the short run. Problem is Hagia Sophia obsoletes so fast. Steam Power gets you the same benfit. I hadn't thought of the larger map issue, however. That's a good point.
It's good in an OCC because it generates good GP points. GE points are hard to get. And those don't obsolete.
That's true, it's good for the GE points - I have seen the Hagia labeled as one of the worst wonders in the game, though. It comes a little late for workers too, and it's improvement construction rate not worker build rate AFAIK.
Its does, but they were comparing it to how many workers less you would need (since you build things quicker) for the hammers put into it be worth it compared to just building the workers themselves
