Hi Turkish Guy,
I practiced this technique of rapid expansion a couple of times before you were back and had replied to my previous question. I did alright. I have it under control now, and am no longer going bankrupt.
I tried it on a small map and got 2 extra settlers by 3960BC! I then got another 2 settlers and a worker shortly after, so I settled with 5 cities to start with. I have to say this made such a big difference to my game it's unbelievable!!!
With that many cities, you are so far ahead of anyone else! I built a batch of 4 extra workers, then 4 settlers, so I had 9 cities very quickly. Then I stopped though, because I didn't get much money at the start - only 100 or so gold
Soon I was back expanding very fast and I tried a different tactic from yours. I decided to peacefully box in the AI by expanding towards them as fast as possible and closing them off so they can't go anywhere (this is normally possible on a balanced or pangea map). I founded religions and spread them to them early so that they were my friends. I then crushed them with my massive culture in key cities next to them.
I have to say, this was really fun. I didn't push my expansion to the extreme, like you did, but the early exploration was definitely worth it. I finished at 1200 AD with a score of 78,900. Not very good but good for me!
I tried another game on a huge balanced map like you did, and I was up to about 60 cities but by then I was so fed up because it was just so tedious. I didn't enjoy just building city after city and micromanaging 80 workers every turn. It was very boring and very slow. You are very patient, and very skilled to have gotten such a high score. Some people have said you got the high score because you used such techniques, but having tried it, I realise you are very good at this, and it takes a tremendous amount of skill and dedication to acheive that. Well done.
...also, building Hanging Gardens as late as possible is brilliant if you can time it right. My score jumped from 68,000 to 78,000 just from that.
