Post a save-game and i'll have a look at it for you.
City micro-management is the key to this strat, you always want your commerce operating at maximum efficiency, and taking full advantage of your Commercial trait. In the early stages, you're trying to minimize growth, so often i will chose for a city to work a cottage rather than a special resource. As soon as your cottage turns from a cottage to a hamlet, it jumps from 1C to 3C. Then move your city to work another cottage square, leaving your new hamlet alone. This may seem counter intuitive, but you'll reap more benefits, quicker if you do. As soon as your city reachs size 2, it'll have two hamlet squares with 3C each, rather than one cottage and one hamlet (4C).
I'll do a nobel game and post some saves as an example.
Please note, like any strategy, it has its counters - early rushes by warriors/horse archers might be a problem, as are raging barbs etc. Its a bit slow to get going, but once it does and you get the Kremlin, you are close to unstoppable.
Wow. I won that game! (I didn't sleep at all and today is a very busy
day but that's not our subject) I started and played from beginning to end
in one session. I saved just once to write the messaga above. I have
won 2 prince victories so far and both of them were hard to obtain. This was
my third and easiest by far. After those 22 turn techs, things started
to get better and better. I think I didn't set the cities exactly as you
described it but I managed to follow the tech path you gave and with each
tech on the list things got better and eveything was so much fun. By
1500 AD when I was maxing out the money still it was 400 golds but
I balanced science and gold (usually at 70 ) and after Kremlin ,
things started to work exactly like you said. I was buyuing 5-6 buildings
per turn. Sometimes 2 wonders

I'll attach 2 saves so if you can check
and tell me my mistakes about the cities, I can even do much better.
Even as I got it, it ruled! Thanks a lot. Definetly a worthy strategy, especially
against AIs. Eveyhthing completes each other like a jigsaw puzzle. State
property + universal suffrage + kremlin + emanticipation + free speech.
Since I was isolated I didn't fight at all. If it was a pangea map,
I'd love to fight with AI after Kremlin

10 units every turn! It was a narrow
space ship victory by the way but I was 3 techs ahead most of the time,
after the civics.
