Yes, I agree with you about Ceuta. I remembered while I was eriting the message, and then I forgot to include it! Too many things in my mind, I am afraid. I am sorry about not stating that Portugal conquered Ceuta and then the city was 'transferred' (so to say) to Spanish control. I wonder why the city did not go back to Portugal after the end of the Portuguese war of independence (in 1665, am I right?) After all, most of the Portuguese empire was returned, and the closest example I can think of right now is Tangiers, which was first Portuguese, then 'Spanish' (meaning the United Kingdom of Spain and Portugal), then again Portuguese, then English (until 1685) and then (I think) it returned to Portugal but I am not too sure about what happened to the city of Tangiers after 1685
Yes, you are also right that Portugal all the Atlantic coast (and I think most of the Indian coast, too) of Africa, until King Sebastiao blundered at Alcazarquivir. I have always wondered about what Portuguese would think about the period 1580-1640, when the whole Iberian peninsula was unified... although at the same time I did not think you would have a very good opinion of the Spaniards!

At the same time, please allow me to remind you that at the time Spain was really a confederation of different kingdoms and principalities, all under the same King but with different laws in each part of the country. In that sense, when one talks about 'Spanish' imperialism during the 16th-17th centuries, it is rather Castilian (i.e., Central Spain) imperialism. The frontiers of the old kingdoms were still there, and taxes were collected when goods had to go from one kingdom to the other. I believe that until the 1700s and the War of the Spanish Succession it would be more correct to talk about the 'Iberian Confederation' rather than 'Spain'. Granted, most of the war effort was made by Castilla, but most of the grants and posts at the Spanish court also went to Castilians, so many non-Castilians (such as Portuguese, Catalans and, to a lesser extent, Aragonese and Basques) felt left out. And when the Spanish government started asking for higher and higher grants of money, the situation grew worse until 1640, when revolt broke openly in Portugal and Catalonia, and severe disturbs happened in Southern Spain, Aragon and Naples. Talking about having -3 Stability level...
By the way, the stretch of barren land between Madrid and Barcelona is called 'los Monegros' and yes, it is close to the river Ebro. However, the part of Spain that is getting closer to being a desert is in Almeria (SE Spain).
One minor note about the map. For what I have seen in the screenshots, the European map follows closely the board game edition of EU. Am I right? I am saking because I have this game at my home, and whereas the borders of other provinces in France, Italy and, I think, also England try to follow what one would call 'historical regions'. I congratulate the map designers for trying to be accurate, and I believe that overall they have done a good job; however, it is a pity that they did not apply the same effort to the Spanish provinces, which are the ones I am more familiar with. What's even worse: some of the names are displaced. I am not the only one thinking thus; you should have heard the comments my friends here in Barcelona said when they saw the map!
