I'll try addressing the comments one by one and I'll split into two posts. I'm sure there are some suboptimal decisions. Aren't there always? When you don't see every turn or event, it sometimes takes some explaining, or perhaps it was just poor decision making.
I only played 7 turns as requested and some builds are just place holders.
First the mea culpa (or is the plural, mea culpae? Sorry, I only know a few Latin sayings

):
Yes, I forgot about the fort, but so far didn't need it.
I did forget to examine the switch to Confucianism and your reasoning. Once we are in FR, you can't have Confucianism as your state religion. Do you still get the benefits of the 1 happy per city? I should have asked about this point.
GM:
Then the path to Econ, use the GM for RP or straight to rifling?
We need a Gm for a corp.
I had forgotten to discuss this in my pre-turn write up, to see if there was any more discussion on this. I'd thought there was someone else who mentioned this earlier, but I couldn't find it. I looked at the options in addition to bulbing most of RP, Settling is a waste, a a trade mission is going to take 6 turns. I went for the immediate benefit as it seemed beelining for Rifles as quickly as possible was the general consensus. It was my decision and I hope the quicker path to Rifling pays off.
Military:
The situation at the start is a few units on the Iron south of Evora, and lots of reinforcements coming. Evora has a small garrison and won't last against a concerted counter attack. Oporto has lots of defenders. Maybe not the best
defenders, but more than enough to resist our attackers or to attack and kill our few units. They were moved back into Evora to provide a better Garrison and await reinforcements. As it turns out, Joao did send 2 HA and a Cat to the tile adjacent to Evora that turn. The plan, as I recall, was to split into two stacks and go after Coimbra and Oporto. Coimbra appeared to be lightly defended. I had to wait 2 turns for enough new units to arrive, and they departed for their designated cities, leaving 3 defenders in Evora in case of a counter attack. Remember they had Engineering for 3 movement and the Iron tile was theirs. Meaning they could have attacked and taken it back. True, we could have then turned our units around and retaken it, but isn't that kind of a waste? In that time Opporto got 5 LBs, 2 XBs, an Axe, 2 Swords, and an Archer. I spent 1T bombarding to bring the defences down and on my last turn attacked. We had just enough units to take the city and even that wasn't certain. All it took was for the RNG to take an ugly turn.
Coimbra which had been defended by a Sword Archer and Cat had suddenly grown to 8 defenders which was more than a match for our attackers. Don't forget, Joao attacked out of Coimbra with 2 Cats, didn't lose either, and damaged our units. As much as I would have wanted to take Coimbra I don't believe it was possible. Perhaps I'm playing to conservatively?
I attached a screen shot of our Troops near Coimbra. I tried to capture a ss of the defenders, but ss in Vista lose the mouse focus when taking the ss. Defenders are 2 Cats, HA, 2 Swords, Axe, Chariot, and a LB
I did have to keep a few units in Santarem and the Ulundi area in case Joao's Carrracks had troops aboard.
Please be patient for the next post, I'll talk about cities and techs, perhaps even the future path.
