War for the Three Han
AD 246, from Buyeo to Kyushu — an ancient East Asian strategy game of thirty-seven strongholds and seventeen powers. One month is one turn.
About this game
A lord-and-realm strategy game in the vein of Romance of the Three Kingdoms IV and V, with tactical battles in the manner of the Koei Gaiden games. Choose a power, work the fields, open the markets, win people over, and bind the scattered Han into one.
The year is <b>AD 246</b>, and that year was chosen for a reason: the middle of the third century is the only window in which Buyeo, Goguryeo, Ye and Okjeo coexist with Mahan, Jinhan and Byeonhan — and with Baekje, Silla and Gaya, which grew out of them. In that same year Wei stormed Hwando and Mahan struck the Wei fort at Girinyeong.
All thirty-seven strongholds sit at their <b>real coordinates</b>. Note that in 246 Pyongyang is not a Goguryeo capital but the seat of the Lelang commandery — Goguryeo moved there only in 427. Play Goguryeo and your first task is driving Lelang out.
There are <b>201 officers</b>, each with a written life and a painted portrait. The thirty-five who are attested in the histories — Guanqiu Jian, King Dongcheon, Miru, Yuyu, King Goi, Seok Uro, Himiko and others — carry <b>the source they come from</b>. The rest are invented, and the game says so plainly. The numbers on all of them are invention grounded in recorded deeds.
Battles are fought on a <b>20 × 14 grid</b>. One officer holds one square, moves, then does one thing: attack, a stratagem, a duel, or hold. Horse cannot enter hills and slows in woods; only bow may climb a wall. Fire attacks work only in the dry months, and a commander gets as many stratagems as his wit divided by twenty.
The thing that matters most: <b>a corps’s strength is its hit points</b>. What you lose in a battle is exactly what is missing on the strategic map afterwards. There is no conversion layer between the two.
Diplomacy runs on declarations, peace offers, alliances and gifts. A peace holds for a year; breaking an alliance turns not only that power but every onlooker against you. Seven events drawn from the histories fire in the months they belong to, each shown with its source.
