If you're offering!
My save right now (because I like to get weird and spend a lot of time on wikipedia) has an independent: Quebec, Nunavut, Manitoba, Texas, Oklahoma (presuming certain treaties were respected),
Yucatan (this would include modern Quintana Roo, too, but that seems difficult) and the
Miskito Nation (modern
autonomous region of Nicaragua).
The game does a good job of making places like Puerto Rico and the Virgin Islands independent.
And you have got me thinking of ways to further expand my pocket universe, thank you !
