I also noticed the map only covers part of the Caribbean. Why no Puerto Rico? Why no lesser Antilles? I was going to say 'The American Government fled to Puerto Rico" but can't do it because it missing.

Well, you can still say that. You just can't play as them. Which is kind of a shame since the island is situated in an interesting spot and has a lot of colonial forts that would still be standing. I think including the oldest colonial fort that is under US jurisdiction, which is a neat fun-fact. The island is also small enough that it may have been spared from direct impacts. Tsunamis may have hit it but I'm pretty sure it's entirely above sea level so the waters may have receded afterwards, allowing for rebuilding.
