A retaining wall is basically a wooden or stone or brick design. Built vertically to hold back dirt and create usable area in otherwise difficult slopped places. I feel Wurm Online has a need for such a thing. Flat-raising and building slabs comes close, but leaves much to be desired visually in my opinion. Retaining walls would be a PERFECT addition to the game imo. There are so many uses for it, and we have no actual alternative. What do you guys think?
