I don't like the UHV much personally. It's a smart idea, for sure, but from a practical standpoint many of the goals seem artificial or unreasonably hard.
I wish the system was revamped to make the UHVs less "epic" but more numerous. After all, from an historical standpoint, civilizations' goals in real life were not based upon an arbitrary "victory" but upon practical needs. The Dutch did not colonize the world so it could brag, necessarily, but because of the resources on other continents. Turkey did not invade Egypt just because it gave them a chip on their shoulder, but for political and economic reasons. England did not circumnavigate the globe because they'd win a prize, but as a result of exploration, etc.
I envision 6 or more UHV per civ, but 4 are needed to win, and all of them can be achieved within the bounds of a standard civ game, instead of making the civ game REVOLVE around the UHV. See?
For example, for England (fulfill any 4):
-Be the first to circumnavigate the globe
-Found 5 cities of 5 or more population in the Americas
-Found 5 cities of 5 or more population in Africa
-Found 5 cities of 5 or more population in Asia
-First to enter Industrial Era
-First to enter Modern Era
-Control a city of greater than XXX culture.
