I must admit I am trying this approach with my current game. It's a technique I have never tried so I can see myself using a modified approach to it. This method involves a few things I have figured out 1) all GP get settles in the capital, 2) build farms and production, forget commerce from tiles unless it's there (spices/sugar/gold/gems etc...), 3) expand slowly, 4) wait to go to war if you can. At least that is what I get out of it.
I am playing on monarch, random huge map (I do not play only a continant map), marathon speed. My guess is this technique may not be so good for marathon speed or huge maps but we'll see. On the other hand starting 2 cities for a long time on huge will keep your enemies away longer and still leave area to expand.
My rules to use this, no cottages in first two cities, after that I am free to build them prudently (I will not spam on grasslands though). I will settle all great people in my gapital with the following exceptions A) Great artists are reserved for I usually do with them since I think I utilize them well and they offer NO production bonus, B) I will use one Great Scientists (if I get one) to lightbulb Philosophy if I can get Taoism first (this is a big advantage I think and would always do this). If I do not get a GS in time, so be it. I will not bulb paper or education though, no bulbibg theology (GP), metal working (GM), or Machinery (GE). Here we go.
So I have tried this approach with a random leader, got Hatsheput. Capital had limited production, built warrior settler (got nice horse city as sister city) went for GW first, chopped alot, got 3/2 of the way before rouge archers came and took Thebes. Game over. To be fair this is only my second monarch game and I noted that barbs come a little earlier so my timing was off, this game was my misplay.
Second game, randomly got Tokugawa on a southern iceberg, on coast, miles from grasslands. Well not the setting I want to learnt his with, I quit this game.
Third, selected Ramses II. Now I know the examples games were won with this leader but he is my second favorite (after Washington), plus industrious will help in getting a big production capital. Start on coast, little production, not what I looking for. I quit this game. Now I do want a fair chance to test this system out, so I want a city with at least some production.
Try Ramses again. Started on an obvious archeopolego map, no neighbors. Got a great starting location, 5 hills, forrests, corn, a seafood, only 4 coast tiles (including seafood so only 3 2 food tiles). Second city pretty good, all hills (settled on one), one seafood, pigs on a hill, but quite a few 2 food sea tiles. I have built stonehenge/great wall currently building pyramids (my they do go fast with so much prodcution). I plan to run 2 priests per city once pyramids are built, then beeline for the oracle with which ever city will get it first (for this wonder I do not care if the GP points are spread out) I really want early metal working, early forges, early colossus (if I had to start this game on a coast tile I want to get to financial status fast).
I will keep all posted how I do. Now I am not the best player here (my god, look at the clash of the war-monger epic, I lost that game very early), so if I can get this strat to work maybe it can be a useful strategy.
