Sorry this took so long. family emergency, which means I'm even more sleep-deprived than usual.
My notes show 11 turns, but the turn count shows 10, so I guess a turn-by-turn report is out.
Rubber: We now have
Replacement Parts, so Rubber has been revealed. Using Mason's Ctrl+Shift+m trick, I see that there are 7 sources of Rubber: 2 on our continent (1 btwn Odense & Izmit, 1 under Crakie's Lake); 2 on the Celtic continent (1 SE of Alecia, 1 N of Verulanian); 2 on the Spanish continent (1 near Toledo, 1 near Valhalla (the Celtic Cavalry is sitting on it); and 1 on the (Celtic-held) island of Lapurdum.
Remnants of war: We started with 3 Celtic units in our Spanish borders. Two (injured) Infantry march off to a neutral tile to heal - they're still there. A Cavalry unit fortifies in place (see above).
As mentioned earlier, I killed 1 Indian Spear, but wimped out on further attacks. CA2 tells me we have 4 Zerks. One was in Bedeville, and it was a merry hunt for the others. Turned out they were all on the East Isle, in Hovd. A Galleon was dispatched to bring them to the Inland Sea.
While looking for the Zerks, I noticed several Musketmen well out of the way in Santanger. Note the location on the minimap:
I dispatch our last remaining Caravel (ironically, the VSS Crazybeard) to Santanger to fetch them back. Since there's a Harbor there, I upgrade to Galleon. It doesn't show on the above image, but a Celtic Destroyer just pulled into Linomn. I decide to leave VSS Crazybeard where it is for wiser heads to deal with.
While shuttling units to the Spanish continents, look what I find:
Diplomacy: As already noted, we started with Celtic units within our borders. I couldn't ask them nicely to vacate, and I wasn't about to give Brennus an ultimatum. Brennus, on the other hand did ask us nicely when our ships sailed through his territorial waters, but didn't folllow up as they sailed on.
Lincoln also snarled at us briefly. Why isn't anyone glad to see us?
We have a ROP with Osman. It expired, but Osman didn't say anything, so it's turn-by-turn now.
Tech: We researched
Replacment Parts and moved on to
The Corporation. The last turn I was able to reduce to reduce science to 0%, and still get the necessary beakers. It put nearly 400g in our coffers. I reset it to 70% the next turn.
Trades:
Sell Silks to Lincoln for 4gpt. (1550). Every little bit helps.
Traded
Industrialization and
Electricity to America for
Music Theory and
Democracy. Also trade
Electricity to Osman for
Free Artistry,
Economics, and 30g. (1565) Brennus will pay 15gpt for Silks, but I decide against it.
Sell Incense to Lincoln for 3gpt (1585)
Trade
Replacement Parts to Osman for 100g + 69gpt; and to Lincoln for 12g +3gpt (Lincoln got a bargain, but my instructions were to gift the techs if necessary).
Now that Celts are at peace:
Micromanagement: I never said I was good at it - or competent for that matter. The next player should probably recheck every single city.
Railroads: I concentrated on making sure every city had at least one rail route to every other city. Finished on our continent, still some work to be done on the SW corner and NW spur of Spanish continent.
Garrisons: I hate ungarrisioned cities, so I moved various units to cover cities (by no means all). I also hate resistors, so I parked a Cav in Izmit, which quelched the resistance.
All spellings on city names is approximate.

Need to know anything else?
