Trade routes benefit competing Civs, but help you, too! The more incoming, the better. The AI should make use of its Trade Route bonuses, so having the East India Company built in one of your Coastal Cities will make it a better target for her ships. Maria I is middle of the road in many stats, so your experience playing against her can vary wildly from game to game. Playing Against The Maria I AI - Their Tendencies (XML Info and Flavors) Warmonger When playing against Portugal, pillaging a Feitoria counts as an act of war. For an Ally you really want to keep, you may even station your own unit there. This would be particularly potent on a hill. The Feitoria counts as a Fort, so you may want to aid a CS by putting it in a good spot - any units defending there will get a +50% defense bonus. The Feitoria will give you one copy of each Luxury Resource the Civilization has connected, which is typically reserved for when you have an Alliance with a CS. The Feitoria comes toward the mid-game and allows your Workers to build this tile improvement in a City-State's borders, but only on a tile along the coast.

The experience gained will usually be about enough to let it go up 1 level if you have built it from a City with a Barracks, so you can tailor them to your needs. The Nau does not gain any combat strength over the Caravel, nor movement, however when it is on the border of another Civilization or City-State, it may use its Exotic Cargo ability to generate Gold and Experience relative to the distance it is from your own lands. It does help with City-State trade routes as well, but you are almost always better off trading with other Civs for the gold per turn is typically double. This is usually 0.5 per resource you have available in your Empire, but with Portugal is doubled to 1 gold per - this can add up to a lot of extra gold with many trade routes going to other Civs. Resource diversity grants double gold for Portugal in each trade route.
