KEEP
The center of every castle is the Keep! I propose 3 stories with a roof, made of 1000 Stones, 500 Blocks, 250 Boards, 100 Bronze/Iron/Steel, and/or 50 Glass if people want windows.
STONE WALLS
Instead of corner posts we will have towers! The first tower will be 500 Stones and 100 Bronze/Iron/Steel. Other Towers will be 250 Stones and 50 Bronze/Iron/Steel. Towers will be 5x5 and provide sight range, perception, and marksmanship bonuses. The wall segments will be 100 Stones for each 1x1 tile, and can be built 3 deep. Turrets (which look like: -_-_-_-) can be added for 50 stone per segment (but only one the edges) and will block 50% of incoming projectiles. The Gatehouse is made of 250 Stones and 75 Bronze/Iron/Steel. It can be used to get on top of the walls if open. Otherwise, use a ladder made of boards and blocks.
DITCHES, SPIKES, AND MOATS
It takes a lot of stamina to dig a ditch. Soil is added to your inventory during. When you dig up 100 Soil, the Ditch is done. To cross a normal ditch, you drop in, and then climb out, causing very slight SHP damage and draining stamina. You can fill it with Spikes made of branches or boards, which cause serious damage and drain stamina faster. Or you can fill it with 100 liters of water to make a moat, which counts as deep water, so you have to swim across OR drop a ladder over it to walk across (ladders will decay quickly if you do this, and can be picked-up or destroyed) You can fill any ditch, spike trench, or moat with 100 soil to remove it. Takes a lot of time and stamina (but not as much as digging it in the first place).
SIEGE WARFARE
Breaking into a stone wall is hard, hard work. You have to break into it segment by segment, which is time consuming and easily spotted. This is where siege warfare comes in! We will have the battering rams still, but they don't do much damage, so you need a lot of time. I will break the new siege warfare into Offense and Defense.
-Offensive Siege Warfare
The Catapult and Ballista are mobile weapons, loaded with Boulders and Bolts respectively. Move 'em into position and fire away. Both require wood, metal, and ropes to build. The Trubuchet is a non-mobile but much more powerful siege weapon that uses boulders. It has to be built on the spot, but has a large range and can easily go right over walls. Ladders are also useful for siege warfare.
-Defensive Siege Warfare
Consists of Wall/Gatehouse mounted weapons and Tower mounted weapons. Wall mounts include Oil Traps, Stone Traps, and Log Traps, which drop the respective object on the enemy. Oil and Log can be set on fire if you activate them manually with a torch, or you can set them to auto and they will drop on any enemy that attacks the wall below them. Tower mounts include Catapults and Ballista which can be rotated and loaded with multiple shots so that you don't have to keep carrying ammo up. Use ladders to get on your wall and knock down enemy ladders before they can climb up!
There my ideas of Castles and Siege Warfare! Almost all of which have been suggested before!!!
