I was finally able to get a playtest in for the Siege of Ulsan game at today's gameday down in Olympia. There were 5 players - 3 for the attacking/besieging Ming, and 2 players for the Japanese - one inside the fortress and one bringing on relief forces opposite the Ming. The Osprey book below was the inspiration and reference material for the fortress (wajo).
As this was a only playtest, and on 6x5' table, I left off most of the Korean forces, as well as some of the Japanese troops. The rules were a modified version of Hail Caesar - which was used before for a Siege of Haenju game (Japanese besieging Koreans during the Imjin War). It worked well, but there are a few things that will be modified for the game being hosted at Enfilade next month. During today's game, it was found that the simplified break test results used were a bit too brutal - basically a lot of units (including supporting units) were being destroyed by failed tests. We also found a good way to have units use the scaling ladders once laid against the fortress walls. If a unit on the ladder is killed off by the defenders, nearby units with enough movement can use the same ladder. The ladder rules have one move needed to reach the wall, another to have it raised, and a final move to climb/mount it for combat.Above: Ming foot reaching the walls, with heavy infantry bringing up ladders. We did a quick mod to the rules to have defenders not being able to shoot at enemy below them within 3" of the wall - too vertical of an angle for missile fire.
