If you all will permit me to go back to part of my original question: that of defense works.
1.Let us tackle the question of walls, first and foremost. I can see this as being a prefab thing that the player clicks from a menu, and then clicks and drags where they want it to be. While it may be a different style based on the culture you go with, is it going to be possible to heighten or lower the walls if you want them to be higher or lower? For the things atop the walls, will we be able to customize the crenelations? Add hoardings?
2.For towers and gatehouses, I cannot see these as being prefabs, but rather be designated as one or the other with the use of doors or arrow slits. For instance, you make a building on a wall, then insert the double doors, portculli, and/or drawbridge to it, and it will let the computer know that it is a gatehouse. With the tower, you add arrow slits or some other item to it, and the computer will know it is supposed to be a tower.
- And now comes a very important question: the question of a donjon or keep. We should be able to have things like arrow slits and portculli and double doors on it, amongst other things, so what will give it the designation of a keep to the computer? Perhaps a throne, which overrides any other designators?
There are more things I can ask about, like if we would be able to put siege equipment on towers, etc, but those three above are more important atm.
