I finally put together a great Korea game for a T200 SV, HoF rules (submitted). I struggled with them in the past, not getting off to a fast enough start and then being behind, missing LToP, etc. Instead of using all 'Friendlies', I included Askia and Ottomans (Babylon, India, Sweden, Morocco, Netherlands), which kept things a little more warmongery and helped with wonders. I missed a late attempt on Hanging Gardens, but got Oracle in expo #2 and both Petra and Macchu in expo #3. I had 4 great cities, but no room for a 5th, which I would have built if there was a decent spot. Some quick notes on milestones and GS, given the recent discussion.
T96 Education
T106-108 Astronomy
*I got Mercantilism before Renaissance, which delayed opening Rationalism. I didn't use Merc until Plastics, as I was putting gold into CS, so built 4/4 schools and observatories
T11x planted first GS, which came from Expo #2 as that built the Oracle
Edit: planted it by capital (observatory + NC)
T137 Scientific Theory. I used Oxford on Radio
T164 Plastics, using 1 GS bulb. I timed Big Ben to finish in conjunction and bought 4/4 labs immediately
*built Porcelain Tower in capital as I expected that to be my final GS (and it was); I normally build it in the capital, but in this game I had expos strong enough to consider (ex. Petra expo)
*Science funding was passed at 2nd world congress (Neb proposed), but it did NOT impact my finish time
T189 produced 9th GS; my 10th would have popped T200 (before factoring in Hubble)
T190 Hubble = 10th and 11th GS
T198 finished Rationlism, faith-bought 12th and 13th GS. I had previously faith-bought 2 GE, using on Statue of Liberty and Hubble
*late-game gold was so strong that I kept all my trade routes internal
Although I wanted sub-T200, I'm very happy with this game and can't think of any major errors. Worth mentioning: I didn't get Reliquary with my religion. If I had, I would have built Hubble and faith-bought a 3rd GS instead of 2nd GE. I had an extra policy, used on Wagon Trains.
Next up, I need to decide if I'll pursue a 3rd civ for T200 or faster, or try and get a Korea game with 5-6 cities. Probably Korea...
