I've always had sympathy for the Pig. His castle is an easy prey for being smashed, his low walls an very vulnerable to catapult attacks.
Try this fortress.
Good points. The order of the opening steps works well. The walls are strong. Tower engines annoy the neighbourhood. Less valuable buildings at the front edges. It seems far harder now to set the village on fire and to conquer the castle at all. Harsh resistance from the wings of the butterfly shape will confront the intruders.
Bad points. Too expensive. Not yet assassin proof.
Bugs. There are 4 tower ballistas encoded, but the one of the rear middle tower is not set up. Something went wrong with the stairs on the way. Stairs 1 and 5 are coded to be sited simultaneously but the lowest step lacks.
In the AIV Editor, (the small) communal gardens have a 3x3 size while in Crusader they are of 2x2. Wanted gardens for the Pig. The shrines do not really fit to his character.
