Yes, playing singleplayer is good fun, but multiplayer is where the real cunning, hate, revenge, and fear come into play. Usually, I like to build my infrastructure, make a few friends of my neighbours, open borders, talk to them, let them know I'm a nice guy and the like. Wealth and research are the 2 most important things, don't worry about invading people yet. Just grab resource rich territory without pissing off your neighbours. Copper is nice, but iron is better. Its nice to have a few of both, however. Horses are useful, but since I'm not an expansive player, I rarely use horsemen. Now, never ever ever neglect your navy. If you're playing archipelagos, this should be obvious. If you're playing Terra, it should also be obvious, or islands, or continents or whatever. If you are playing Pangaia, a strong navy is THE best weapon you can have, because NO one will expect it. You can move troops MUCH faster by sea and you can suprise the hell out of your enemies by landing troop ships at their coasts. Now, I'm giving away lots of my secrets, that help me win big time, but thats ok, I expect you guys to add to my work. Think of it as an Art of War, in the making. So, science (libaries, observatories, universities and MONASTARIES!) Money. Markets, Grocers, Banks, Stock markets, whatever you can get. Harbors are great and underrated. Make sure you open borders with people you trust! The trade revenue can mean the difference between 70% science at a deficeit and 80% science and a surplus. Also, make sure you have atleast 4 armies of mixed type in each of your border cities and costal cities! Always treat your coastal cities as vulnerable! Now onto my award winning WAR strategy, its rather simple. I pick an aggressive civ, usually with financial. Like the Incas. Since they have mysticism, I found a religion as soon as possible. You can build your economy as much as you like, but for this tactic you must have a state religion in all your cities, switch religion civic to theocracy, and make sure vassalage as a civic too. This gives you nice experienced troops, make sure you have barracks in each of your cities too. So your troops will get the free combat I upgrade. Then upgrade them to combat II, then give them the amphibious upgrade. Build a few caravels ASAP, get astronomy, gunpowder and chemistry as soon as possible. Then build a good force of frigates and galleons. Usually I like 5 frigates and 5 galleons per major coastal city I want to take. then pump out grenadiers or riflemen. Scout with your caravel, find the best coastal city you can find, like one of those players that builds 15 wonders, and has like 24 population. Make sure you have atleast a 3:1 ratio of grenadiers and riflemen to whatever he has. Even if its warriors. Load your troops onto a ship, make sure your 5 galleons with 15 grenadiers/riflemen and 5 frigates are on the same tile place them 3 squares away from the cultural border of your enemy, so the enemy can't see your ships, and make sure you can get them RIGHT up to the enemy city by the next turn. Next turn, bring your 10 ships, 5 frigates, 5 galleons with 15 grenadiers/riflemen to the coast of the city, get your 5 frigates to bombard, then get all your troops to just unleash into the city. if you caught him off guard, you've just taken the best city in the game. If not, you're probably screwed and hes gonna turn his peaceful Gandhi-esque nation into a war machine, pumping out tons and tons of units. So anyways, I usually get 3 strike forces of these. Pick 3 of the best coastal cities my enemy has, then on one turn, use all of them to attack your enemy, and usually I grab 3 major cities with ease. However, I recommend you raze them, not keep them. Because if you keep them, you will lose them. Just raze them. Anyways, thats my award winning naval strategy. Remember, Combat I -> Combat II -> Amphibious! DO NOT attempt this without amphibious troops and DO NOT land your troops on their coast and then attack the city the next turn. They will have a full turn to upgrade their troops, bring in reinforcements and so on. Bad bad bad idea. Attack the city DIRECTLY, do not pass go, do not collect $200. Then raze it to the ground. Most players will scream and cry after their coastal capital with 15 wonders has been destroyed. While you laugh. Anyways, I hope this has been informative, and I hope I wasn't too redundant. And excuse any grammatical errors, I didn't edit it. Its a great strategy and it always works for me. and to defend against this strategy: build galleys, caravels, frigates, ironclads and whatever else naval units you can get to defend your coast! Do not let people do this to you! Anyways, if anyone else wants to add MP strategies, please go ahead. If you want to add on or improve my strategy, please do so.
