Stonehenge? That´s a brand for an instantaneous soap...
The way to win with the Portuguese is by taking the most of its traits:
- expansionist - build 2/3 scouts on start of game and pop every hut, denial strategic resources from AI - horses/iron;
- seafaring - after the first scout build a curragh, it will move 3 turns in the water, making it easy to find everyone on the map before all others;
- in sum, Portugal can map the world like no other civilization in the game and get all the contacts you need, try to read some articles on what techs the AI usually research and you just have to what others dont, allowing you options of trade, after getting all diplomatic contacts, concentrate on diplomatic rounds every turn in order to get the maximum out of every one;
- With the scouts + fast curraghs you´ll get a big advance on techs, play with sci great leader
on, and you´ll rush the pyramids;
- Use the terrain to your advantage, since Portugal has no industrial, agricultural or commercial traits, you need to build your cities on rivers/lakes always (aqueducts are expensive), on a CxxC display, and most important with at least two or more
forest tiles in it, the chops for a rushing grany/barracks are essential.
- Always build The Colossus, this one is very important, try to beat the AI in building this one, since this is probably your best chance in getting a golden age, if not you still have The Lighthousse;
- Don´t forget as seafaring your cities have a bonus commerce in water and harbors are cheaper;
- Military: Try to resist the urge to connect your strategic resources, or if you cant, pillage them before you decide to build up troops, a legion of veteran warriors/chariots is much easier to build and faster then a swordsman/horsemen giving you more turns to concentrate on the needed infrastructure - granies, barracks, temples, libraries, harbors, marketplaces and so on. Also, read up on a poor man´s army, it´s important when playing Portugal.
- In the hands of a skilled player and with the knowledge of how to exploit the AI, Portugal can be a very dangerous civ.
- Finally, The Carrack, a 2/2/3(+1 movement with lesser chance of sinking provided by seafaring and +1 also if lighthousse) unit that can carry 3 units and trigers your golden age, well if your playing a massive continents map either single player or multiplayer, this baby can make everyone´s head spinn, if you made things right you´ll have astro before all others and a lot of currags/galleys and harbors just waiting to upgrade, make it so! go forth and settle, conquer everything.
Just to have an idea: Carrack is as good as Frigate but costs 20 shields less and carries 3 troops, making it much easier to build and comes earlier on the tech tree.
- In sum, a couple forest chops, fresh water, The Colussos/The Lighthousse and a lot of exploration and diplomacy are essential for Portugal to win, establish embasssies, spy one or 2 cities, trade luxuries trough harbors and turn fations against each other.
- Starting with Alphabet, you can slingshot to Phil also. Try to change government, republic/monarchy.
- Try not to lose your scouts, when you get astronomy you can upgrade them to explorers and these are the ultimate spies.
- Try to avoid researching Magnetism, you dont really need it (except to jump to industrial agem but your glory days are on stil on the middle ages so why not polongue it) will make your Lighthouse obsolute, plus Navigation will give you trade over the ocean tiles and Magellan´s Voyage for +1 movement in sea totalizing to a 6 movement carrack and a golden age trigger if you not had it in the past.
