Got prolonged a turn or two because Churchill went Mercantilism too, as the last AI, so then I lost all good trade routes and 20% research rate (about 380

to 300-ish)
Kept a watch on the Monty-Joao was, which seemed to be getting out of control, and just when I may have pulled the trigger and gifted him PPress to gain peace, they peaced out on their own. Looks like Joao paid Education for it. Phew. Elsewhere, Churchill created Lincoln as a colony.
Don't recall what other trades we did, but it wasn't much. Monty is looking pretty dangerous here, tho. He too got Steel this turn, and must have gone there directly after self-teching Chemistry. Hasn't started plotting again yet, but I'm sure it can't be long when he has Cuirs + Cannons.
We got Education with somebody (Joao I think), and not many lacked it, so therefore I did this, despite giving up semi-monopoly on Chemistry.
Looked over things again, and had to pay a little for Edu+Chemistry for Replaceable Parts with Churchill, so he must be close to Edu too. Therefore made sense to carry out the trade, altho Chemistry is probably available on the market now. When only Isabella had it, it should have been safe I think, as she trades at 60% and isn't Friendly with anybody.
The situation then looks like this. Many have Cuirs by now, which is always dangerous, but nobody has Rifling yet, tho several are getting close.
I've lined up Military Science for now, as I've found recently that it's nice to upgrade Maces (Samurais here) to Grens. Before I basically avoided that tech, and went for Rifling instead. Surprising that nobody else have gotten Liberalism yet, which means that only HC can tech Communism at the moment. He is probably doing either that now, or the hated Democracy (funny, huh).
Capital size 14 now, but think I need to 3-pop the Bank next turn. Will be going more back-and-forth between research and gold going forward, and not least when we declare, so it will come in handy. It has the only monastery in the empire, chopped out a few turns ago. Wanted to save those 24-hammer forests until it got a state religion.
AP Hinduism has spread in a few cities, but I haven't bothered with AP temples yet. Have focused on getting out units instead, tho mostly slow-built. The Heroic Epic city Osaka could 2-turn trebs, which was quite nice (and had a few forests too), and it has also built a couple of muskets and knights. I need some Pikes too, as they are decent Cuir defenders, especially on hills. The city can now 2-turn cannons, which it will probably get busy with for a loooong time (23 base hammers).
The overall empire looks like this (doesn't show some cities up north, that are still not ready for unit production). Also have a settler, finally, for the southern horse city. Have surely whipped the NE island too heavily, but it was nice to get out some workers there, the missionary from the random Buddhism spread, and also this settler.
Am reasonably pleased with the amount of units. Not quite ready yet, but 8-10 cannons is a decent amount to start with. Need more boats first.
Currently we have defensive pacts with Huayna Capac and Boudica, because why not

The plan is still to declare on HC, I think. It makes most sense now when I'm in Buddhism (only in a few cities for now, as it's recent). Hopefully they stay out of the war, tho I can't vouch for some of the others. HC does have the AP, but he recently went Free Religion, which probably neuters it a bit.
Pondered about striking further south, like the desert hill outside Tiwanaku, but probably better and safer to land up north on the hill there. Then march on Cari afterwards. No nice defensive hill there, but what can you do.
