I didn't end up following your advice Annares, though that would have worked too. I was just getting weary of war weariness I guess. Worked out ok.
Preturn: Things look pretty good. I move a few units. I see we have an empty army ready for us getting Cav.
IBT: Heraclea Deposes us. Nicomedia Deposes us. Both towns had a single Trebuchet in them.
Incas build Shakespeare.
910 AD: We destroy Nicomedia taking it back. A lot of units are injures so I let them heal this turn.
IBT: Inca makes peace with the romans and we get lose spices. I cylce ahead to prevent riots after first city.
920 AD:
WW seems really really nasty. I still don't understand how our WW can be that bad with Rome. We need recovery from the WW, so I am going for peace and head toward war with Sumeria. I am striking out into unknown territory, so here goes; wish me luck:
1) Byzantine will trade Metallurgy and Physics for 113 gpt and peace.
2) Attempt a careful tech steal from Sumeria: Success. We have Mil Trad.
3) Inca have no tech but they do have spices. I trade for it for horses and dyes
4) Rome has nothing to offer so I go for straight up peace so we can break it if we wish.
Ok, I really don't think the Byzantines will declare war if they catch us stealing so:
5) I try two steals off the Byzantines; the first succeeds, the second fails and Theodora is not pleased. We get Magnetism that Sumeria does not have, but they won't trade (even if we wanted to which I don't think we do. They might get Nationalization)...
Start upgrading
IBT: Shoot! Constantanople deposes us. Just not having any luck with that. It was getting pretty far down in pop too.
930 AD: Our upgrade cost just doubled, but there is nothing we can do about it. This was a bad time for that flip. A gather forces for Sumeria.
IBT: Not much
940 AD: Sumeria is now Industrial. I think I want to hit him now before he gets rifles. Next turn perhaps.
IBT: Not much
950 AD: I try an immediate steal from Sumeria. They catch us and we are at war. I ally with the Byzantines to destroy Sumeria.
I Capture Hyberiad and Madras.
IBT: A Cavalry Attacks and loses
960 AD: My armies hit Calcutta and another Sumerian city (forgot to write down the name. Both are razed. I decide that risking WW for flips with the other two is not a good idea and rase those as well.
IBT: Several units show up. We win more than we lose.
970 AD: Kill the enemy units.
IBT: Another musket guarding a 3 cav is offed along with one of the cavalry. It is hard to defend everything.
980 AD: Healing of armies. I build a bunch of temples push back borders.
IBT: Another city flips this one has a few squares overlap with Constantanople. I am getting bad luck on this.
990 AD: I kill units and heal some more. All Sumer's Resources were close to the border. We captured both Salts, his iron on the first turn and just got his horses.
IBT: Our capture of the Saltpeter on the first turn seems to be working. There are fewer Cav.
Portugal makes peace with the Inca and Byzantines.
1000 AD: Capture Der, Nagsu, and Marad. I kept them to block enemy movement. We may want to abandon after things are under control.
Notes:
We are completely overpowering the Sumerians. I don't see anything stopping us from taking the entire continent. Both they and the Byzantines lack resources.
I traded our iron to the Byzantines for the MA vs Sumeria.
I think my plan from here on out would be to attack and destroy Sumeria, then go for the Byzantines. After that go for a weaker civ on the other continent. If we keep them at war we can keep their unit counts down and so go for domination. I don't see anything that is going to be able to stop us.
