Read title. Well, Vanilla gave us UUs, Warlords gave us UBs, why not have BTS give us UWs? Think about it: There's lots of cool wonders out there in the world. But not all can make the cut. For instance, the Great Ziggurat of Ur. It's really cool, but it couldn't even pass off for a national wonder! But, we could have it in there, unique to the Sumerians! It could replace the Pyramids, and have the government civics unlocked, as usual, but, also giving you extra espionage. What do you think? Another example: The Great Obelisk. A really good tourist attraction, but it's dwarfed compared to others like the Pyramids and the Sphinx. So, for Egypt, we could have Stonehenge replaced by the Great Obelisk, which will give you a free priest or two, along with Stonehenge's benefits! Why would the Egyptians need Stonehenge anyways? Consider the idea please. Who knows, there's a 0.17% chance that I might become video gaming history if this works! It's either me or the "Penguin Units Possible?" guy!
