Just wondering, because on Archaepaligo the AI's spam these cities a ton. The way I see it, the only way these are worth it is if you have portugaul, the netherlands, or carthage, b/c of their UB's. Otherwise, you have to whip/buy everything, with one hammer per turn in that city. Even with all the commerce, it still isn't really worth it. And yes, I know wonders (Moai Statues, The Colossus) will help, but let's just suppose we have no wonders. For now.
