I can scarecely believe it myself, but here it is:
Rhye's and Fall of Civilization: Korea Variant for
Beyond the Sword. I hope I got the download right; I'm still a little punchy from a trans-Pacific flight.

So, yada yada yada download and unzip into your BTS Mod folder. Launch Civ4:BTS; select "Advanced -> Load a Mod -> RFC Korea." After it loads, select "Single Player -> Play a Scenario -> RFC Korea." The scenario is a modified version of the 3000BC Locked scenario; all civilizations are playable. The Koreans replace the Maya, so they are the last to load.
Details:
Civilisation: The Koreans
Leader:: Wang Kon
Starting Turn/Year: Turn 144 / 65 AD
Unique Power: The Power of Astronomy (All techs cost 40% less until the end of the Middle Ages)
Unique Building: Seowon (Available with Civil Service; replaces University; research in city +35%)
Unique Unit: Kubokson (Requires Sailing, Metal Casting, access to Iron; replaces Trireme; movement =3, strength = 3)
Unique Historical Victory Conditions:
* Control three cities in Manchuria [i.e., by building or conquest] by 1000 AD (See image below for boundaries)
* Build a Buddhist Stupa, Taoist Pagoda, or Confucian Academy by 1400 AD
* Be the first to discover Printing Press
Core Korean areas: The Korean peninsula and a few tiles to the northeast. Sanshan will not flip.
Basic starting army: 4 Archers; 4 Swordmen; 1 Axemen; 2 Settlers; 3 Workers (spawn two turns in). Additional units may accrue depending upon what was in the area when you spawned.
My notes:
* I can't guarantee that there will be no Python exceptions, but the modmod runs fine on my computer at least. Post an alert if there are serious problems, please, though I'll probably be switched if I can figure them out.
* Whether the UHV is easy or impossible seems to depend upon the luck of the starting situation. In one Monarch-level game I won by 1420, thanks to quiescent neighbors. In another, I had to fight wars with both Japan and China, but still managed the UHV by 1450. And in a third game, China waited ten turns after I spawned, then declared war and rolled in a massive Stack containing multiply-promoted catapults, swordmen, and axemen; I was quickly exterminated. Overall, I'd say that the Korean situation is a lot like the Egyptian situation: the UHV game is short and pretty easy if you know what you're doing, but their long-term survival can be tricky.
* I may yet modify/strengthen the Kubokson unit. Right now it is basically a coastal-only Caravel, which means it has a 75% chance against any Trireme with which it has matching promotions. But Japan likes researching Optics quickly, so to give the Korean unit a longer shelf life I'm open to giving it an extra strength point. Please forgive the fact that it is available earlier than is historically accurate, as it needs to be available this early if it is to meaningfully useful in deterring/fighting Japanese incursions.
