I think America as a playable civ takes precedence in this case.

And finally, I doubt this will fly but I think Frankfurt should be replaced with Munich one southeast. From what I know about modern German history, Munich has always been a larger and more important city than Frankfurt.
New Spain is... painful, to say the least. Spain was declining, but with those maintenance costs, tech penalties, and general lack of population they're gonna be hard pressed to do anything at all.

What did I say when I committed the scenario?
Sorry, I didn't explain that well; I meant even after all of the population adjustments, improvements, and buildings added Spain's city placement is still too close to allow them much of a chance to do anything useful. La Paz, for example, has only 6 workable tiles, two of which are jungled over a third which is a single-food coast. That city is nothing but a money/science drain (even with Machu Picchu since it still drains science). Mexico is pretty bad as well...
Because they were in personal union even before.Why is Scotland under English control in 1700AD? http://en.wikipedia.org/wiki/Acts_of_Union_1707
By 1700, and throughout the 18th century, the Spanish Empire in the Americas was a drain, and the Spanish were in bad shape. So it's appropriate.
Also, it shouldn't be so bad with proper infrastructure. They'll be able to run some science, etc. But the Spanish will appropriately start in the lead and steadily lose ground to the other Europeans and other powers.
-Daibul could be moved 1W and renamed Kolachi, later to be renamed Karachi, around 1750 (Daibul wasn't significant later on)
Putting a city in NZ to represent maroi i don't think is needed. Much like placing cities in Australia to represent the Aboriginals is also not needed.
