Slider at 10% culture is 3
I am at, basically, 90% of my normal economy. But if the 3
allow for more than 11% growth, then it is to my advantage to do so.
This will only occur if my cities are close or at their happy cap, and the new tiles they work are worth it. In addition, this allows for more valuable trade routes and greater production.
Additional production mitigates cost of Hippodromes
Additional worked tiles mitigates 10% economy loss
edit: Also, if you gain more happiness from other sources, you can decide later on to keep the existing population.
At least, that's what I've been thinking. You also get a Globe Theatre out of it for a food happy Great Person Farm.
I'm assuming that I'm not the first to think or try this. How have others found it? Oh, and I guess this isn't limited to the Byzantine, just that they have a building most specifically dedicated to making it more efficient.
