I suggest practicing. You can just go create games, and play around with the tech order and build order in a variety of circumstances. I have one going right now, I wish I hadnt started it with "Locked Modified Assets" or I would have done the WB Save myself, its a beauty!
BTW, its HARD on the economy to beeline HBR. I am thinking now that I will prioritize it, but without improved tiles to work, it just slows the game down far too much. Bare minimum is Mining, BW, and Ag. I also love to have the GW on these maps, just for the spy points, but that takes another tech. I will still have a fairly early HBR compared to other games, especially since it also unlocks our UB, but Ag and Mining are just to strong to hold off. My plan is likely something like AH >> Mining >> BW >> Ag >> Archery >> HBR. If I have stone or Marble, I will stick Masonry in there as well. GW is still a possibility too, if there are enough forests and/or stone nearby.
Its also harder than I thought to get a couple Woody II warriors, even if I constantly wander them around. The best plan seems to be setting them up on forested hills and hoping a Barb Warrior comes along, because animals just dont last long on Pangaea maps, the AIs have roaming scouts and such everywhere.
BTW the game I am playing as practice has a similar "Great Wall as an offensive weapon" thing happening, LOL. I spread a line of 3 cities to cut off the AIs, and had stone in the 2nd cities BFC (where horses were as well) so I built the wall, and sure enough, all the barbs are travelling right through the gaps to get to the AIs, LOL. I am getting some of them to hit my XP-seeking Warriors, but I lost 2 Wood I warriors doing it that way, heh.
