I saw elf's emporer thread and though I would make my own thread. I play Emporer games pretty often and can usually win. I wrote a strategy guide pre patch that had a minor following.
I used to prefer Catherine and chopping was a major part of my strategy. I would commonly win small/standard games around 1100-1300 AD with grenadiers/cossacks. Also in the majority of games I played without a state religion. I skipped all wonders in favor of science/commerce buildings and military.
Now that chopping has been nerfed, I've changed strategies. I usually play the Incans. I try to found buddhism and use religion for the +happy and culture. It's pretty easy to get it to spread to my other cities and in some games it becomes the dominant religion on my continent.
People think to think quechas suck but it just isn't true. They are great worker stealers and city raiders. Also, since barbs start attacking around 2500 BC, you need early defense. Quechas are cheap and kick archer ass. They do expire early but they allow you to skip archery and postpone bronze working - if you are in to that sort of thing.
I've been taking some pictures of my current game and am about ready to start my first offensive. Have a look:
It's a standard fractal map. I prefer to play marathon because I like the slower pace.
Here's my starting location. The gold is nice but I would prefer to switch the pigs for some wheat or corn since HC starts with Agriculture. AH is a rather expensive tech and this will force me to research it early.
Since I start with Agriculture and Mysticism there's no point in building a worker first (nothing to work!), so I build a settler. I'm also going to research meditation to found buddhism and get some culture going. The yellow religion fits well with HC's colors. It also allows me to build monasteries and opens a path to priesthood (Oracle + temples).
Got it. Hopefully it'll spread to one or two neighbors. Sometimes it'll spread everywhere. When that happens it really screws up the game. Same religion = less conflict. Less conflict = AI spending their hammers on commerce/tech instead of war. It also doesn't help when warring within the faith results in a lot of negative "you attacked our friend" modifiers.
Second city location. Looks like I'm in a corner. Is this game over already? Gold + Corner is a recipe for success. Looking around my corner and I find out that the gold is my only pre-calender/monarchy happiness. Good thing I have a religion. I build some quechas to fight off the barbs and a worker to build some roads to spread my religion and hook up my resources.
Third city location. So far all locations look pretty sweet. Lots of food and hills with a bit of river action. Cuzco + Tiwakinu are going to be manufacturing powehouses. I like to run beaurocracry and build the heroic epic in the capital in the middle of the game to really pump out units.
Oracle. Free tech! I'll take Metal Casting. Thanks! With only three cities and room for two more. I don't need courthouses yet. I can research those when I begin my first war. Let's get some early forges in my cities and possibly the collossus. Early forges will probably get me in the top 2 for production even if I'm last in land/pop.
Fourth and fifth cities go up. So far I've met Bismark who shares a border with me and Alex who has Bismark's back. Alex loves to backstab. Seeing as buddhism spreads to Alex and Bismark is Jewish, he'll backstab Bismark. Hopefully he'll wait until I'm ready.
#1 GNP. Average/Last in everything else. Pretty normal. I expect to lose the GNP lead to 1 or 2 AIs. Since every AI on emporer pays very little in maintenance per city, they can afford to settle as much land as they can. By the time they get Calender they can work the 50 Calender resources in their border and take a commanding pop/gnp lead. It's inevitable. I do expect to go up in production when I finish my forges.
Haha. Sucker.
As you can see, I'm going to Monarchy early as I have one grape vine to work and I really need the hereditary rule happiness boost.
How about that! I couldn't build it in my capital since Cuzco isn't on the sea. That's good and bad. It won't pollute my Priest GP points which will guarantee me the Mahabadoobe but it also means slower Great People generation. Nothing I can do about that. 4 commerce sea tiles will be nice while they last. The game wil probably end around 1550 AD so that's a major portion of the game.
I'm researching Alphabet in anticiaption of making a couple trades. I skipped over Iron/Sailing and would like to trade Metal Casting/alphabet for those as well as Math/Calender/Currency.
Met a couple more AI. Louis and GW are warring - Thank god. GW left alone is a terror. Religion is varied. Excellent. Lots of fighting.
Looks like Berlin holds the Pyramids. Bah, who cares about the pyramids. I'm already running hereditary rule.
Here's where things stand now. After I got Alphabet it looks like Alex is the one with the GNP lead. It could be GW though. As my cities grow and begin to work those 4 commerce water tiles, I'll be making bank.
Just noticed those previous images were kinda small. Here's a better size.
70% science with 5 cities. #1/2 in production. #2 in GNP. Researching CoL. Yep, I'm ready for war.
Bismark is a douche. This should be a cakewalk. I'm already planning my next victim - Alex. Toku has had his border closed the entire game and has no religion. Another moron.
OK planning my first war. I'm planning on building 10 axes/swords and 2 spears. I'd prefer to build mostly swords (7.2 str is much better than 5.5 and Bismark is mostly defending with archers and spears. Unfortunately I just traded Alex for Iron and I haven't finished mining it so it'll be mostly an axe invasion.
10-12 should be enough to take Dortmond and Frankfurt. Then I can regroup and take Berlin. The question is whether I should raze and rebuild or take them as is. Personally I think Frankfurt overlaps too much with Berlin. AI really pisses me off with their city builds. They always overlap too much.
What do you guys think? If I did raze I would move Frankfurt two squares south and move Dortmond one square southeast.
