Just out of curiosity, what is the deal with the lack of accents in the city names? I remember some reason was stated long ago but I do miss them from normal RFC and they were possible there.
The Portuguese (so probably the Spanish as well) city names for Madeira and the Azores are a bit sketchy. Right now it seems as though all of the names are from the Azores and Madeira is unrepresented. The error here is kind of obvious, somebody mistook Madeira for one of the Azores because the name that comes up is Ponta Delgada. There is a two tiled island in the Atlantic with salt and sugar on it in between the Azores and the Canaries. That is Madeira. It's location is a bit off in our map, should be more to the right and a little more South. Google Maps? The correct city name for both of its tiles is Funchal.
The Azores are all in the right spots, but the southernmost island's city name should be Vila do Porto. One more island to the North, where the most desirable spot for a city is, should have the name Ponta Delgada, the historical largest and most important settlement on the islands. The other islands on the very edge of the map should be Horta.
This probably isn't a big deal because the islands almost never get settled but it is a glaring error in the map.
