Being able to have palisade walls placed up or down hill would be a great addition, Clearly palisade doors would need to be on a horizontal/flat piece of land. It would allow some houses or forts to be built on hillsides or slight slopes and remove the need to flatten a football sized piece of land 100%.
I found a picture of what I mean. Granted it only give the idea.. not the scale.
Would be amazing to see and not feel so architecturally planned like boxes.
Just a Idea
