@LuKo: sorry, I thought the argument was yours, so please forgive me. But in any case, all Europe is already well crowded. As you see in the map posted by Edungeon, we pretend to gain some tiles to the sea, what is equal to create more space. But in central Europe (in
your meaning of Central Europe, not my point of view) it's not overcrowded, but any addition of cities will definitively sature the area.
@Edungeon: yes, I'm Spanish, and the land I've been born, Galicia, (the small patch of Spanish land to the north of Portugal) it's very culturally linked to Portugal. We were part of the same kingdom for many years, until they became independent. In fact, Galician and Portuguese lenguage share the same origin, and Galician people doesn't have many problems to understand Portuguese. Here is my opinion about the things you've posted:
Map: it seems OK. I'll give you a more defined opinion when I can see a capture from the WorldBuilder.
Flag: the last one it's OK, too. Or you could make a dual color design of the first flag, something like the attached image.
UB: hmm... I'm thinking now on the Concelho, wich will be a Courthouse which will give an additional -25% to manteinance. Portuguese colonies always have been very autonomous, what allowed them to have a empire that spread all over the world, as long as most of the affairs were done by locals. That will reflect on the game on such reduced mantainance.
UP: it should be something economic, more than naval, but can be tide to the sea, I agree. What about +1
on coastal tiles?. It can be entitled "The Power of Fishing Fleets". Portuguese have been always entitled to be master fishermen. Trading their fish allowed them to earn money, used to buy other things, in a growing spiral. Search for new places to fish, encouraged them to go abroad and discover new lands.
UU: the Carraca, with the effect you said (allows to carry settlers). Nau was the Portuguese word for "Galleon". I know it because in Galicia we used a similar word, "Nao" (my grandfather did used it), but today it's not such common, and we preferably use the Spanish word "Galeón".
UHV:
-Be the first to circunnavigate (yes, it's used already, but here we have the civ that historically did it).
-Have three cities in Africa, two in Africa, and one in South East Asia (Macau it's in China, and was founded by Portuguese, and the island of Gao was near India) by 1600.
-Not to lose any city until 1850 (which will mean avoid the historical defeats of the Muslim invasion, the Alcazarquivir disaster in Morocco in 1578, and specially, the invasions of the Napoleonic period, that caused Portugal to move its capital to Rio de Janeiro).
And another aspect,
spawn date: it should be about 1100. The reason is that before, Portuguese identity was not clearly formed. In fact, Portugal was divided between the muslims and the Galician kingdom. Only the fall of the latter, and the capture of Lisboa allowed the forming of the Portuguese kingdom. Even on this period, Portuguese did not spoke Portuguese, but the primitive Galician. The creation of the frontier between Galicia and Portugal, A Raia Seca, started the separation of the two nations, political and culturally talking. After that, the rise of Portugal was parallel to the fall of Galicia, that lose its independance forever.
BTW, how will you manage to make it for Vanilla?. I thought there was no way to introdce more than 18 civs... It will be great, if you can, as long as I like more RFC for Vanilla than for Warlords (less and stronger civs, and less bugs are the main reasons).
