Kit at a glance
Sejong the Great steers Korea's seowon science with a scholar's hand: his reign rewards deliberate research milestones with surges of progress, keeping Korea's traditional tech lead while adding flexibility the queen's version never had.
Opening: the first 60 turns
Sejong's opening is about hills. Scout the capital area, then settle so that a hill within two tiles has no other district planned around it; the Seowon delivers its full science only when nothing else touches it, and mines placed beside it add science on top. Open Scout, Slinger, Settler, Builder and research Mining, Pottery and then Writing, since the Seowon unlocks from Writing like a Campus and Korea wants it as the first district in every city. Civics run Craftsmanship, Foreign Trade, Early Empire, and the extra culture Sejong earns when Korea crosses into a new era means the civics tree keeps pace without Theater Squares. By turn fifty aim for three cities, each with a Seowon placed or under construction.

How to play it
Seowons still hate neighbors — isolate them on hills, then build the city around that constraint. Ride the science lead into whichever finish fits the map: spaceports, or hwacha lines that make invading Korea a historical mistake.
Victory paths
Science is the default and the Seowon is why: flat science in every city regardless of mountains means Korea reaches Education, Printing and the Industrial era before anyone, and the space race is a matter of building enough Industrial Zones to launch. Sejong's era-transition culture surges change the secondary plan compared with Seondeok. Culture is realistic here because those surges keep civics moving, letting Korea pick up the Theater Square civics and tourism policies without slowing research. The practical pivot rule is to check the civics tree at the start of the Renaissance; if Korea leads there as well as in techs, add Theater Squares and a Great Work economy and go for a culture finish while the science lead keeps rivals honest.
Synergies: city-states, wonders, policies
Pingala belongs in the Seowon capital from the moment governors unlock, and his base title boosts exactly the science the district was built for. Natural Philosophy is the policy card to slot as soon as Recorded History arrives, and Rationalism later rewards the same high-science cities. Among city-states, Geneva and Hattusa suit the science plan while Nan Madol and Kumasi support the culture pivot; Kilwa Kisiwani is worth the hammers because both types get amplified. For a pantheon, God of Craftsmen adds production to the strategic-resource mines Korea places beside Seowons. Wonders that repay the investment are the Great Library early, Oxford University later, and Kilwa; Stonehenge and other faith wonders are a distraction for this leader.
Weaknesses and counters
The Seowon's demand for isolation fights against every other district's desire for adjacency, so Korean cities are laid out around a single constraint and end up with weaker Commercial Hubs and Industrial Zones than they could have. A hill-less start delays the whole plan by many turns. The science lead attracts denunciations and coalitions, and Korea's answer, the Hwacha, is a Renaissance unit that cannot move and shoot in the same turn; before Gunpowder the defense is generic. Sejong's era bursts also tempt players to rush eras through cheap techs, which leaves buildings unbuilt behind the research. Rivals beat him with a Classical or early Medieval invasion, or by pillaging Seowons, which are usually on exposed hills at the edge of the city.
