OVERALL STRATEGY
Contender game, because I wanted religion this game.
The
great drkodos' prediction of a triple whammy (no easily accessible bronze, iron AND horses) caused me to consider a Feudalism slingshot. And after exploring for those tasty grape vines, how can I refuse? After weighing Feud slingshot vs CS slingshot, I decided that Feudalism path would be better for my empire.
Wang Kon Kim Il-Jung being Financial automatically means Cottage (+ Camp and Winery and Gem Mines) Spam trumps Specialist Economy.
Actually I have forgotten to rename my leader as Kim Il-Jung so far. But I'll get around to it.
INITIAL CAPITAL BUILD
Wow, a coastal start with no coast resources.
Seoul's build was Worker, Warrior (to size 2), Archer (to size 3), Settler. Then I build nothing but Archers (also whipping a Granary somewhere) until I am able to build Oracle.
EXPLORATION AND EXPANSION
I first explored North, seeing the wine site and that just screamed I GOTTA RUSH FEUDALISM! I stopped exploring north upon seeing the 2 gems, pig site and went west, spotting Tokugawa's... EXPOSED WORKER! I waited for it to get to the borders and I steal it!
I escort it back home (boy was I sweating every step the warrior + worker took) and he made it! I had two workers early game while having only built one, which I consider a tremendous advantage since I had to rebuild the fur camps a lot of times.
I grab Monarchy pretty early, making the "super site far from capital" (my third city) much less attractive for me than to settle the wine spot immediately.
Cities, cities, in order of appearance
1. founded Seoul on the spot
2. founded Pyongyang west of the wines (see drkodos' screenshot)
3. founded Wonsan to grab the 2 gems, pig, ignoring the bronze
4. attacked barb city in jungle north of Wonsan
5. founded fourth city (forgot the name) at where the barb city was in drkodos' screenshot
TECHNOLOGY AND MILITARY
The Oracle is kinda built late (700BC+), I was confident I could get it, what with me leaving the Wall and Henge to the AI. I didn't need the Henge anyway since BUDDHISM = MINE! Boy, I really love that feeling.
Tech Order: Meditation, Hunting, Archery, Agri, Wheel, Pottery, Mining, Bronze Works, Priesthood, Monarchy, Writing, Feudalism (free tech), Alphabet, Literature, Math, Construction...
Acquired from trade: Fishing

, Sailing, AH, Polytheism, Iron Working, Masonry
And I'm currently researching Code of Laws, expecting to take Tokugawa's cities with my Longbow + Hwacha army. Pyongyang just expanded borders enough so I recently got Bronze, but so far (530AD) I have a whopping 0 Axemen and Spearmen, but over a dozen archers, at least one Longbow at every city, with Longbows and Hwacha already parked at the doorstep of Tokugawa's nearest good city (after they razed one of his cities in a bad spot).
Poor Toku, he's about to get a taste of deadly pyrotechnics. BTW I didn't rush him earlier, because I wanted him to expand first so I didn't need to build as many settlers.
Speaking of "dozen archers", the fog-busting operation got pretty nasty in the BC's.
RELIGION AND WONDERS
Being Financial, Korea and all, and I've never founded Buddhism, I decided, I gotta have Buddhism this game. And I did! I jumped for joy, danced around, and... wait a minute, you didn't need to know that.
Even though this game is "Raging Barbs" I didn't go for the Great Wall.

But as a result I needed a much larger archer army than the people who have the Wall. As a side-effect I was able to use some of them as MP (monarchy police), and soon, they will keep the peace in cities taken from Japan.
Built the Mahabodhi with the Great Prophet from the Oracle + 1 priest specialist. I needed the Priest to get the Great Prophet faster before I finish the Great Library.
I hope to get a scientist next.
I was going to do a modified CS slingshot with the Prophet then I realized that I needed Masonry to research Construction. So much for that, but I research quick anyway at this stage thanks to my wines. It's only a matter of time until I research CS manually after code of laws.
in short, my wonders are (in build order):
Oracle, Mahabodhi, TGL
