When and how do you get workers and how can you do this early ICS without getting declared on?
I farmed Monty for Workers. I stole his around turn 10, won the war, and stole two more just after turn 60. I picked up the fifth Worker from a barb camp, and built the sixth in the capital.
By this point I've disbanded them. After the Railroads went up, there wasn't any point in keeping them around.
What size do you grow your cap to while spamming warriors? is it better to just stop it size 2 and swap to a hill for faster warriors? or is it better to let it keep working food to grow as large as it can?
Grow baby grow. I let it get to 4. I aggressively work Food tiles, then switch to Hammers when I'm ready to stop growing. You may have to live with a size 3 cap if you don't have something like that Cows tile in the radius.
You mentioned building siege units to help keep border cities safe, but I don't see any in your picture. It looks like you only have a Knight and an AA gun (people really build those?) guarding your whole empire. Did you sell off your army at the end of the game to get extra cash? How did the military situation play out for you in this game after you attacked your first opponent? Presumably they wanted revenge at some point...
You can't see the shooting war with China in the bottom right hand corner (it started up for the fourth time that turn). I've got four or five Rifles (the legacy Warriors) and three Cannon down there that you can't see. If I'd had the cash, I'd have upgraded further. (I could have gotten the cash with a loan, but what I had was good enough.)
Monty wasn't really a problem. He had two cities for most of the game, one was up in the ice, and I bought up the Horse tile there so he had zero strategic resources. He tried to take me on turn 110 with Archers and Spears. It wasn't pretty, although he did manage to sneak his Settler through my lines.
China was more of a problem, but I had siege that was a generation better than her armies until the very end. Only Washington made it to Industrial that game. Not sure what Genghis was doing; he was the clear runaway, and he apparently couldn't be bothered to build Science buildings.
Quick note on fighting China - Chu-Ko-Nus are evil. You pretty much need to Trebuchet those things and keep your army out of range. The Longswords didn't really become useful until Knights and Muskets started showing up.
The AA gun was a gift from Dublin, which allied me during the early war with Monty. I was pretty excited, since I had nothing but Longswords at that point.
This is an awesome guide! I was wondering if you have any shots of your final tech tree. If you had them along the way that would also be cool to see. Just trying to get an idea how much you skip. Do you basically Bee-line all the way with a few off shoots?
I either am working on Combustion or just finished it. I skip everything on the bottom, using a turn of research in Fertilizer and Metallurgy to avoid getting them from Research Agreements. Once I had all the spaceship techs, I went back and started researching that portion of the tree.
