So that's all the teams:
Team 1 Japper (Kongo) /Mikeforall (Khmer)
Team 2 Emperor K (Germany) /TheArchduke (Russia)
Team 3 BrickAstley (Rome) /Singaboy (China)
Team 4 Woden (Nubia) / ChevalierMalFet (England)
Germany/Russia is a great pairing and I think there's a decent chance that TheArchduke and Emperor K end up as the biggest competition. The Kongo/Khmer setup is a bit of a one-trick pony, while Nubia and England don't appear to be great pairings for this particular map. Nubia is still a good choice and will be stronger if it turns out that there's more desert/floodplains elsewhere on the map. The England pick is hoping that there's more water to be found than what it sounds like this map will have. Still, uncontested control of the Great Admirals could be very dangerous. Interesting to me was no one picking Gorgo or Australia given their reputation in other PBEM games.
Now in terms of thinking about the starting positions:
We should probably think about how we want the early game to play out between the two civs, including where to plant early districts and which player will try to land which boosts. The nice thing about the starting terrain here is that both locations are strong enough that they can go settler before builder if desired. One of the two players will want to go builder before settler to secure the Craftsmanship boost and ensure that Rome doesn't get stuck waiting on that civic to complete. I think it makes more sense for Rome to go builder before settler, allowing Rome to boost and then finish Craftsmanship civic, which will boost it for China before China even gets a builder out. That would open up China to go settler before builder, and potentially use that early settler to grab a location with stone for the Stonehenge play.
Long story short, I'm thinking something like this for opening build order:
Rome: military unit -> builder -> settler
China: military unit -> settler -> builder
So which starting location is better for which civ? I actually think either one can go in either spot without too much trouble, but I lean slightly towards making the eastern spot the Roman one as Singaboy suggested. Short list of reasons why:
* The main goal of the first builder is to secure the Craftsmanship boost and unlock other boosts in the process. The eastern spot gets more value from an early builder than the western one, which has little for builder to do in the opening turns. Therefore put Rome (going builder into settler) over in the east, and China over in the west.
* The first Roman builder can improve the wheat tile (Irrigation boost) and the sheep tile (Horseback Riding boost). There's no important third tile to improve, probably a plains hill mine as the last one for the boost. The wheat and the sheep are helpful though, since the eastern city is slightly food-poor compared to the western city.
* China may seriously want to consider moving one tile east onto the plains hill to get the 2 production center tile plant. That also get the amazing 3/2 spices tile into the first ring. China wants to get the 5/0 sugar and the 3/2 spices in play ASAP, then add the 1/3 plains hill forest next to the spices at size 3. This also saves the forest on the starting tile for chopping later. I think I'm talking myself into this move now that I type it out.
* China is also better for the western spot because there's desert in that direction for the future Pyramids and Petra builds.
Tech paths could also be tricky in the early game. China really wants to get Astrology unlocked quickly to be able to lock in the cost of a Holy Site while it's cheap; with luck, hopefully China will find a natural wonder to speed that along. China also wants Irrigation quickly because all of its resources are improved with that tech, so China can actually skip Animal Husbandry and Pottery for a little bit. Rome has a tougher early research path, wanting Animal Husbandry for the sheep, Mining for a potential plains hill mine, and then Irrigation (to take advantage of the wheat farm boost) and Writing (for an early Campus lock-in). Rome may actually need to skip Mining early on and simply go AH -> Pottery -> Irrigation, using the third builder charge on the bananas. That's probably fine since there are a pair of 1/3 plains hill forests for Rome to work after growing to size 4. Heck, improving the wheat tile with a farm and the bananas tile with a plantation gets Rome one additional point of housing so it's not even a waste.
Obviously a lot starts changing as soon as the map gets revealed with more scouting information. What else are you guys thinking based on the screenshot we have now?
