Lisbon is a GP farm that I fear other teams already own.
I'm not sure what makes you think so. Phoenix Rising played the same opening as us and went for the Turn-55 Alphabet approach, so they didn't go after an early Bronze Working. Turbo Ants went for an even earlier Alphabet approach that matches with our early test runs of settling 2 Cities on the same River and skipping self-teching of Fishing, which also means no rush to Bronze Working. Without early Bronze Working, no one will be successful with an early Chariot rush.
Thinking we might position our Berlin warrior 1S and hope we get lucky.
Nope, it's too late. Berlin has 99 Culture. It's either this turn or later when we declare war. I'm not sure about the overall team sentiment, but I am not comfortable with attacking a Warrior with 50% odds and then having to defend against a second Warrior in between turns.
The silver lining is that Frederick does not yet have The Wheel. So, if we head to the north-west with Warrior 1 right away, there's a good chance that we will be able to steal Frederick's Worker up by that Sheep if he goes to improve it before he learns The Wheel. That's exactly what we can do in the test game (try it out in the test game, where Frederick is busy researching The Wheel and heads to that north-west G Riv Sheep with his Worker next).
Going any further south with Warrior 1 gives us a very high chance of meeting the Light Blue AI, so that's another reason to head north-west now.
Does southern warrior need to head back to Paris as MP unit?
That's correct. We need to move Warrior 2 into Paris on Turn 42 at the latest.
Lisbon will also have 99 Culture now, so its Cultural Borders will also expand in between turns.
In the test game, Joao's Worker just builds a bunch of Roads in silly spots. It would have been nice if he would have sent his Worker to the PH Riv For square on which our Warrior 2 is now standing, but that doesn't happen in the test game, so I hold little hope for it happening in the real game.
We could theoretically camp out Warrior 2 on the GH For that is 1 NE + 2 N of Joao's Horse until Turn 38, but it might be better to move him sooner, say, on Turn 37 or earlier, so that we don't end up forgetting and thereby delaying our Paris Library.
In the test game, which seems to match the real game for what Joao's Worker has done, the Road 1 W of Lisbon will be completed next turn, so we could move 1 W P Riv For Road and then move to the P Riv For square that is 1 NW + 1 N of Lisbon all next turn.
We just need to avoid going toward the south-east and we won't meet the Yellow AI. On our way back north, we can simply avoid Yellow by doing something like moving to the P Riv For that is 1 NE + 1 N of Lisbon, then moving due north-east from there.
The trickiest micro for the next little while will be remembering to work the Cow in XO Cognac on Turn 36 and to steal back the Fur in Paris on Turn 36. Other than that, the City micro plays itself for the next little while.
Once XO Cognac has built its Work Boat, and we remember to switch to working the netted Fish with our second XO Cognac citizen at that time, I will suggest that we put 2 turns of Hammers into a Warrior, after which point we will grow to Size 3 and we'll need to remember to start building a Settler there.
I wonder how soon barbs will cross borders, a barb warrior in fog between Paris and Berlin could be end of game.
On a crowded map like this one, I wouldn't even worry about it.
In an absolute emergency situation, we can build a Warrior in Paris in the span of 3 turns, which is just enough turns needed if a Barb Human Unit were to show up at the edge of our visible area to the east of Paris. Plus, we have a Scout that we could stuff into Paris, too. Thanks to our spawn-busting and the Peaks to the east of Paris, plus the crowded map, though, it's a non-issue.
Worker moves and builds are pretty much set in stone until T50.
Yes, although what we do after Camping the Deer is debateable.
I'd probably say:
T36 Finish the G Cow Pasture
T37 Move to 1 SW of Paris
T38 Move to the Deer
T39 Camp the Deer
T43 Move 1 N (1 NE of Paris)
T44 Road 1 NE of Paris
T46 Move to 1 SW of Paris > partial Farm > STOP
T47 Move to the Horse > partial Road > STOP
T48 Pasture the Horse
T52 Finish Roading the Horse
We don't need a Road on the Deer in order to connect-up the Deer, whereas we'll want a Road 1 NE of Paris for our north-east City.
Who wants to take this turnset?
There's a chance to finally be able to steal Frederick's Worker on the G Riv Sheep that is 1 NW + 2 N of Berlin.
There is some micro to remember, but it's not very intensive.
We have very limited ways in which to move our units, so there's no real room for creativity, but it's an important turnset for getting us toward Alphabet without meeting more AIs.
I tried to attack Portugal with Chariots in the test game but it did not work well. Either way Portugal has to go fast.
In the short-term, Portugal may be our best trading partner, since Stalin won't trade techs, Churchill may not trade techs until he meets someone else (say, Portugal), and we may be at war with Frederick (although we should be able to take a Cease Fire by the time that Alphabet comes in if all goes well).
It would be nice if we let Portugal build us at least a second City, both to make it less likely that he'll stuff 5+ Archers into a single City and to benefit more from a war.
He's still building Work Boats for us, having just build the 2nd of 4 needed Work Boats.
We also want to make sure that once we start our warring, we've got enough critical mass to keep on capturing Cities. Portugal is out of the way and can be marginalized for an easy war later. I'm wondering more about how we take down Germany or England efficiently, as Portugal looks quite blocked in. We might even want Portugal to settle an overseas City for us to easily capture later.
Theoretically, Portugal doesn't have to die, assuming that this map is geographical, but Berlin would have to fall. Berlin's Riverside Copper is an annoyance that won't be trivial to deal with, although maybe we'll just end up making Germany much less of a threat if we can steal its Worker on the G Riv Sheep.
I'm not saying that we won't take out Portugal, but they're an easy target to plan for and I'd rather that we put on our thinking caps in terms of figuring out how to effectively take on either Germany or England.
We also need to have a plan for The Great Lighthouse. Assuming that we'll build it in XO Cognac, we might be short on troops early on, but failing to build that Wonder will probably cost us any shot at the Golden Laurels.
Lisbon isn't a practical location for putting The Great Lighthouse, as it will take too long to capture it, get it out of City Resistance, then send a horde of Workers down to there just to Chop out that Wonder while racing against other AIs who may have also been gifted a Lighthouse at the start of the game.
EDIT: 1 AI has 90000 points for Population while another AI is stuck with a Size-1 City with 1000 points for Population. We're 4th with 49000 Points, just a bit above the average.
There are 56 (56 - 54 = +2) citizens in the world, 5 of which are ours.
Turn 35, 2600 BC EP values
