There was a thread for Spain in this section, but i'm not able to find it. So i'm opening a new thread. In that thread i read a very good idea: razing Marseille before French born and flip it. It works! It means more space for Barcelona, no tension on french border, and one french costal city less, useful to win the race for first colony in new world. The second very important move for Spain is to get Rome and its shrine: gold is very important for economy, because colonies are very expensive until colonization civic. In european cities do not build anything but religious buildings, jail, lighthouse, and later markets. For other buildings, just wait for renassaince era and use settlers to upgrade all your cities in one shot. The matter of this post is something i discovered in my last game with Spain: Krak of Chevaliers!!! You can build it in Cordoba, with presence of islamic religion, and its effect is a citadel in every city. Citadel is the spanish UB, with extra culture, useful to enlarge lands in south america and get the silver in the other side of Andes. To keep islam in Cordoba, you do not have Teocracy, otherwise Islam disappears, and you cannot build Krak. You can change to Teocracy later, before Academia, of course. Some tricks: delay conqueror events as long as possible. If you get Conquistadores, the conquest of Aztecs and Incas will be a piece of cake. Try to found protestantism before HRE, to keep control of holy city (in my case it was Madrid) and discourage other civ to convert. To defend from those native Dog Warriors in America, heavy spearmen are more effective than Tercios. Keep 3 heavy spearmen on the copper in the south, and 3 heavy spearmen in the hill east of the gold in the north of SA. It is a very funny game.
