OK, here's an update:
In short: I razed Kagoshima, settled another town next to Edo and actually did a little bit of research towards RepParts. Still building up our forces. We haven't got strong enough for an effective invasion yet, but Cav production will be doubled in 2 turns.

1570AD: Rushing Cav in Edo.
1575AD: Rushing cav in Edo. Rome as Electricity, JPN has learned Corporation. We still have that prebuilt going in Beijing which would do nicely as TOE.
JPN: CORP = 4240g
ROM: ELEC = CORP + 4740g
Turning on research for MED. Still doing 630g.
1580AD: Rushing Cav in Edo. DOW. Attacking Kagoshima:
vCav > eRifle: eRifle loses 3hp, vCav dies
vCav > Rifle: defeat.
Razing Kagoshima, getting 4 workers. Capturing another 2 workers and parking them uotside of Edo and defend them with the 2nd rifle and 3 cavs. The rest of the cavs are fortified in Edo.
IBT: eSamurai attacks Rifle, defeated, vSam defeats Rifle, vSam defeats Cav, 2 vRifles attack Cavs and make them retreat, capturing back their workers.

rushing Cav in Edo.
Notes: The turn SM is learned the palace prebuilt in Beijing has to switched to TOE via the big picture. I suggest Replaceable Parts as the 1st tech.
VIKs still don't talk, maybe they are in AI agony.

Orebro has flipped yet, I kept on trying propaganda. We can rush another settler in Edo in 4 turns.

Shall I play on??
