Hello back to you and welcome to civfanatics!


I've been browsing these forums quite frequently the past few days, reading PDFs and checking the Strat forum as well as just generally browsing but there are still a few things I'm unsure of, which I may have missed in my studies.
(I'm currently playing BtS as The Vikings; Noble/Terra/Epic settings with time victory disabled)
The concept of a settler rush: I'm just not sure exactly how soon after founding my first city I should have more cities set up.
It's not very wise to expand extremely quickly in civilization IV (it was a good move in civilization III). In civilization IV, cities cost upkeep and because the income is fairly limited at the start of the game, this upkeep can become too much when you expand very quickly. So you'll have to make sure that cities actually contribute to your empire. Investing lots of hammers into a city and city defenders and then just letting that city sit there won't do a lot of good for your empire. You have to make sure that each city contributes to your empire as quickly as possible as otherwise, they're just dead weight that will pull your civilisation down.
To get these cities up and running quickly, you need a sufficient number of workers. As long as there are cities working unimproved tiles and as long as forests exist that could be chopped to speed up the development of your cities, you know that you could use more workers.
At the very start of the game, your capital is completely unimproved and building a settler at that point to start expanding your empire is a very time consuming thing. A typical capital will produce 5 hammers (from food and actual production) when building a settler at the start of the game and it won't grow during this construction as the food is invested into the settler. It's better to first improve the food and hammer output of your capital by improving tiles around the capital. It takes a while before the capital will be productive and can produce its first settler. The second settler won't take as long as the capital can now produce quickly. Just make sure that these cities actually contribute to your empire as quickly as possible and don't drag you down.
Also I always end up with sick & angry people in my main city. No matter how many farms I build nothing changes.
You probably missed the happiness and health values next to the production and food bar at the top of the city screen. The starting health and happiness values are pretty low and are quite limiting. As a city grows, it's unhealthiness and unhappiness grow by 1 for every population point that is added. Once the unhealthiness exceeds the healthiness, the city will become sick resulting in a loss of food. Once the unhappiness exceeds the happiness, some citizens will become unhappy. Unhappy citizens still eat food but don't produce anything.
The only way to solve the issue is to increase the health value and happiness value of a city. There are many ways to do this which are nicely categorised in these two articles:
Ways into happiness by cabert and
Ways into health by cabert.
Often, the ways to increase the health and happiness of a city are limited at a certain point in the game. More options will open themselves at a later date, but at that specific point, the options are limited. Thus you want to make sure that the city just doesn't become so unhealthy and unhappy by limiting its growth. You can do that by switching from high food, low hammer or high food, low commerce to low food, high hammer and low food, high commerce tiles. Using the rush production option from slavery is another method to transform excess population into something useful: hammers.
The end goal of a city is not to become big, it's to get a high hammer and commerce output.
Note that producing lots of farms actually had an adverse effect as it made the food production of your cities even larger and thus resulting in faster growth and bigger cities with more health and happiness issues.
Third: No matter what I do I just can't seem to get ahead in my military production (going for a domination victory) because I think I'm spending too much time setting up cities (which kinda ties into my first problem) and trying to bee-line for berserkers which takes a long time for me. Are they generally worth it or should I stick with axe/sword units?
You should just use the units that you can build when going to war. It's no use postponing war to wait for that perfect unit that will come someday. Of course, it is also not useful to go to war when there's no prospect of any actual gains. Make sure that you're stronger than your opponent. Scout his lands before the war and take a look at the Power Graph (F9 screen) to guess the strength of your opposition. And very important, don't go up against well defended cities without lots of siege equipment. Use siege units to remove the defence bonus and use a few collateral damage attacks from siege units before sending in the non-siege units.
War is a costly affair in civilisation IV. You'll lose units, your diplomatic relations will suffer, you'll lose trading opportunities and trade deals will be cancelled, your enemy may pillage some of your lands and last but not least is the war weariness unhappiness which will appear in your cities making your citizens unhappy and inactive. The gains of a successful was are also considerable. You'll gain cities, the basic building blocks of your civilisation, greatly increasing the strength of your civilisation while you similarly weaken one opponent. The cost of an unsuccessful war is that your empire will stagnate because of the costs of war while your opponents empires will grow further.
If you can't produce enough units for a war, then your cities might not be productive enough. It's always a good idea to create a few cities that have a high production (lots of mines and enough food to feed the citizens that work these mines) and can produce units quickly.
Lastly, I end up in war because people keep asking me to cut my ties with everyone else and I just say no until they get annoyed with me. Any tips on how to handle this situation?
You can't be friends with 2 people who hate each other. They will continuously ask you to chose between them and when you don't, then they'll start to hate you too. The idea is to pick a limited number of civilisations who are likely to like each other (same religion) and become friends with them. If they ask you to break your ties with someone outside this limited group because they don't like that civilisation, then you should seriously consider doing that. If they ask you for a small favour, then you should also consider doing that. Even war against a civilisation outside the group of friends should be considered. You can't stay completely neutral in this game. You're often forced to choose a side.
Diplomacy is an important aspect of this game, don't neglect it. It can be one of the more interesting parts of the game if you get into it.
