Ah, I get it. I hadn't got the worker first, cities later component. Makes sense. I suppose you stay with one city moderately long unless needed to get copper.
Btw, I know what a plains/hill gives a city tile. What do you get for Ivory or Stone or Marble?
Also the connection to crowded maps (I usually play Large w/ about 10 opponents instead of 8). Why the preference for Fractal over Pangaea? & have you considered Great Plains. A lot of resources, but VERY concentrated by region (West: Silver/Gold/Sheep/Dye; Center: Wheat/Cattle/Gems; East: Corn/Pigs/Sugar. Pretty much nothing else except C/I/S/M, and the last two are rare. No Ivory/Silk/Bananas at all in my current game).
I suppose this would not work nearly as well on Normal speed, since tech would advance faster in relation to Axeman mobility.

I generally stay at one city longer than any Civ except the ones I am attacking. Another benefit of the extremely early attack strategy is that they go into a mode where they build only archers and workers as long as they don't get a huge surplus of archers (at which time they might try to squeeze out a settler). My second city is almost always intended to get me either copper or horses and I generally don't found it until I know for sure that I can get one of the two.
Ivory, Stone or Marble on a normal plains square (i.e. no hills) acts the same as if you founded on a plains hill (i.e. you get 2 production from your capital square instead of one). Since none of them give great benefits when developed they are ideal to found on top of. I *always* move on top of those three if it is a one move jump from my starting point. Also nice that they get hooked up immediately once you get hunting or masonry and they cannot be pillaged. It works the same for copper and iron but you can never see them to start the game. Always a pleasant surprise when copper pops underneath the plains square you founded on.

Stone, Marble Copper or Iron on a plains hill is the holy grail. It gives your base city *3* production which is pretty insane early on (I haven't gotten this in a long time but assume it is still the same). My best game ever was founded on a plains hill and copper popped underneath when I got bronze working. I was playing Mansa and never even bothered to get Archery until I could trade for it.
I go with Fractal because Pangaea is too easy and predictable especially with this strategy. I found continents to be boring/unrealistic maps. I haven't tried Great Plains because (I thought) they were all flat worlds and I have never cared for flat worlds. More a preference thing than any reason. I do vary map size although I don't play huge for computer/lifestyle reasons (I want to have a life). I will occasionally do a Pangaea but not with the better leaders.
I might have to give Great Plains a try. The one map I started on it a while back was interesting but I bored with the game quickly for some reason (I suspect some bad battle luck put me in an ugly position).
I think it might work well enough on normal speed because as long as you keep them from hooking up a strategic resource (such a key part of the strategy) they can't do anything but archers until Feudalism. For a badly beleaguered, tech suppressed nation it takes a long time to get to Feudalism even on Normal speed (I used to play normal but switched to epic after the first 20 games or so). You might be right though, it has been a long time since I played on normal speed.
BTW, I love slightly overcrowded worlds. Seems like a lot more action especially prior 0 AD. It also makes the worker grab/eternal warfare strategy (4,000 year wars are common in my games) a little easier to execute (if nothing else you aren't ferrying workers across huge expanses of territory to get them back to your cultural border).
