I've been a lurker in these forums for some months (as the BNW got released) and have tried 4-5 of the latest TSG - it's been fun, I've learned a lot, so decided to share some thoughts. It is up to T160 though, so not exactly opening action, but for me this still felt like "early" action. Apologies, if this is against the rules.
Domination is not my usual victory, but from what I've heard, playing Zulu could turn out rather fun!
- What did you consider in your decision of where to settle your capital?
Settled on the nearby hill as I didn't want to waste more turns on finding a "perfect" spot.
- What were your initial priorities?
I used several advice from Moriarte's liberty domination victory guide and Glory7's Zulu domination guide, so I pretty much followed the recommended policy and unit/building order. It is for Deity, but I believe it's useful advice nevertheless, basically you learn alot by reading how they reflect around, well, everything
Building order in the capital: Scout -> monument -> scout -> granary -> shrine -> 4 archers. Two scouts made it easier to explore this map. Not convinced about whether shrine was very useful. As the initial pantheon bonus I took +1 culture from pastures because there's lots of them around. But is this extra culture actually gonna be of help? Also, my capital grows slowly so I might have to boost it with food caravan. Or simply accept that it's not gonna have any super impressive outputs.
Social policies - will follow Glory7's recommendation of maxing liberty -> commerce
- What tech path did you follow and why?
Pottery -> archery -> mining -> masonry -> calendar for cotton & wine -> construction -> bronze working. I was very confused about Writing and how much I should focus on science at this point.. but I know I need education and those universities up at some point
- Were there any early wars and who started them?
First conquests - Shoshone-Brazil
I started planning the war against Pocatello when building my ranged units and took Shoshone as soon as I felt confident. He sneak-expanded way too fast, and he also stole Pyramids, which was unforgivable. Burned the city he planted next to my capital, took over Te-Moak and Moson Kahni - all were rather weak. I almost think I could have gotten Shoshone earlier!? Their capital conquered around T100. The location was tough and I spent quite some time planning the movement. He built Great Wall couple of turns before I invaded which was actually quite funny. My army at this point = 4 composite bowmen, 1 warrior and also 1 newbie spearman and 1 newbie catapult.
Moved on to Brazil, but did not attack before I upgraded my ranged units and got the impi. Took Sao Paulo and Rio. I chose not to eliminate any civs so both Shoshone and Brazil were generously left one city each.
Although I think the start of this game has been smooth, somehow I have wasted lots of turns! Nevertheless, Brazil was out around T160.
On the positive side tho - none of my units died. They have quite some experience now. I've managed to pretty much balance the game and thus I do not suffer any serious setback a la "oops, -12 happiness, where did this come from". I have two DoF with Venice and Germany. I have 3 cities of my own, and 4 conquered cities, access to several lux resources and.. LOTS of pastures. I'm sitting with 20 something Horses in total and alot of productive cows and sheep!
The other wars/conflicts so far - Germany took over Assyria rather early. There's also some tension between Germany-Poland (really?

) and Portugal. Perhaps this opens up for bribing a DoW between some of them at some point..
- How did you use your UU?
I trained impis before attacking Brazil. They seem to be a very good melee unit, although at this point the conquested cities haven't exactly been very hard. I guess their unique bonuses helped them with everything - to stay alive, kill the enemy units, provide protection for ranged and invade the cities

Right now the movement bonus is what I like lots! Still, I'm also very impressed by my crossbowmen right now.. hoping to turn them into mad killing machines with Logistics and Range
Yeah
- What differences did you have to consider in this game versus G&K?
Hard to comment, although I did play some G&K. Perhaps the big changes like religion, tourism, caravans, policy-tied world wonders? I can't really see any obstacles or problems, but perhaps it's the lack of experience of G&K?
