We are slowly growing populous and powerful, and have taught the Mongols a lesson.
Interturn: Why have we irrigated riverbanks? Is this the auto-worker at work?
Pop-rush temple at Wonson? Yes. Maximum efficiency how, and growth is stunted anyway, until we improve land. (I think it may have been

-- settling up here so early.
Our reg warrior takes Mongol elite warrior down to one hp ... then dies.
Seoul builds sword, set to sword.
Japan is building GL! So they have lit, too.
530 bc (1) : Military travels to western front.
(i) Mongol archers approach outskirts of Karakorum.
510 bc (2) Patroling horse kills reg Mongol warrior. Military movements.
(i) Japan wants to parlay. Peace for (our) tribute of 180 gold? "Not a chance."
Pusan trains spear, begins sword.
490 bc (3) Elite archer takes out Mongol archer.
(i) Alliance with Indians vs Mongols expires. Indians remain at war, however.
Seoul finishes sword, starts temple. (Subject to change.)
Nampo trains settler, starts worker.
English build Pyramids, in York.
Several Japanese warriors emerge from fog in north, approaching Wonsan.
470 bc (4) Mongols will no longer give philo for peace! We have some military built up and in place. Let's cause them some pain and see if they grow more reasonable.
China has construction. Price for alliance against Japanese is lit, WM, 320. Sounds expensive, and seems unnecessary. Will trade construction for lit, wm, 270 gold. Sounds expensive.
India will ally against Japanese, and give us philo, for lit, 240. This is tempting. It might keep the Indians occupied, softening them up for us later ....

After reflection, I decline.
Horse kills Mongol archer; elite archer kills Mongol archer. Wonson worker taken off jungle clearing (aargh. But we don't have the military up here to defend him).
(i) Chinese start Great Wall. English complete Colossus, at York.
450 bc (5) Regular warrior emerges from Wonson to defeat reg Japanese warrior.
Troop movements. I'm putting together a stack on the western front to move against Almarikh.
430 (6) Stack attacks Almarikh. Pult misses. Sword defeats spear. Archer defeats spear. Wounded elite Mongol warrior remains in city. I move more forces up for next round.
410 (7) Almarikh razed. Mongols will give philo, all his gold (12), for peace. But not his maps? Okay, philo, 5 gold, wm for peace. Done.
Our continent (assuming that spit on the nw corner is not an isthmus) is a good size: with us, the Mongols, the Japanese, the Chinese, the Indians. There is some choice territory well to the nw, unclaimed, between India, China and the Japanese.
Gandhi has nothing to offer for lit. (Well, 1 gold. No thanks.) Chinese will sell construction for lit, wm, 260 gold. Too steep, and the tech can't be brokered because the other civs are too poor.
(i) Forbidden Palace message pops up.
Pusan revolts. Doh!

, sorry. They get a scientist.
390 bc (8) Japanese warrior, archer approach outskirts of Hyangsong. (Diverted from Wonson? I left Hyang undefended for a turn, not as an exploit, but to finish off Almirkh.)
Seoul finishes sword, set to temple (veto this if you want, but we now face no credible threats and it might be a good time to slip in a little building).
370 bc (9) zzz
390 bc (10) Mongol sword moves into our territory near Karakorum. Grr. Are they looking for round 2? Or just taking a short cut to their war with India?
Sword kills Japanese warrior. inch'on founded, on coast.
I check for brokering opportunities. India has currency, Construction. Currency can be had for 250, and China doesn't have it? I take the plunge: currency from India for 250 gold; construction from China for currency, wm, 50 gold. Mongols have both already?!?
Peace from Japan would cost us 100. I leave this question to our next leader.
Mongols and Indians still seem to be at war, in a desultory way. Some Japanese forces are approaching P'yong (which I had stripped of its spear), but I have moved some forces into the area for reinforcement.
I left the garrison in Karakorum unmoved, in case we wanted to strike against the Mongols (violating the peace). Even if Genghis does commit a dastardly strike, however, we have strong defenses in place.
Good luck to our next leader!
