If I should make a separate thread for this let me know, I was just starting here in case it was some singular step I was missing. Here's hoping it's not "git gud".
I used to play Civ4 a lot when I was younger. However it was always on Settler and it always followed the same pattern. I kicked everyone whatever continent I started on, rocketed past them on the tech tree, and proceeded to fly to other continents and nuked civs which still relied on longbowmen for their main defense. I recently started playing again, and figured a good first step to making the game more engaging was to up the difficulty. I cranked it all the way up to the terrifying (default) Noble (there are a lot of difficulty options, I don't want to know what horrors would await me on Deity), and got started. I knew I was in trouble when barbarians attacked and conquered one of my cities and I had exactly one archer each in my other two cities. I managed to fight them all off, found the single other civ on my continent (ha, unlucky AI started on it's own isolated peninsula, easy kill), and started cranking out knights. Then the unexpected happened, they declared war on me, and a score of Cuirassiers crossed over. I open up the score tab to talk to the other civs to try and figure out where on earth they got horses (early scouts said there were no horses on the continent that I did not control) and tried to figure out how they were so far ahead of me tech wise with half the number of cities that I had. That was when I discovered I was on the very bottom of the score list, by a lot. The top guys had ironclads and railroads.
I feel like I'm missing some key steps in order for me to have fallen so far behind. Watching the game replay shows that the AI's absolutely explode in city numbers, but with every city I build my economy goes in the toilet and I can't keep the research value up. I'm building courthouses and other financial buildings, connecting cities and resources, building hamlets, priority wealth production in all cities, and yet I just can't keep my economy up with the maintenance cost of building cities.
I started another game with the intent to actually pay attention and try to stay on top of research, but I quickly realized (before even meeting another civ) that I was so far behind every single world wonder was being built before I even reached the tech level to start construction.
Quick and dirty advice:
Build between 1 and 1.5 workers per city
Settle each city with a food resource in the first ring of tiles around the city square
Beeline Bronze Working, revolt to slavery. Whenever you have citizens working unimproved tiles, use them to rush improvements.
Chop your forests for granaries, workers, settlers.
Build granaries in every city, forges in almost every city. Build libraries in your capital and in 1-2 other high commerce cities. Build barracks in 1-2 of your high production cities that will build units. Don't build other improvements anywhere except in your capital (and not even there, in most cases).
