Its not hard to put a moat around a deed which is what I'm currently doing, placing some bridges for access and its starting to look how I'd like it.
But.
I do have a serious problem in that I cannot think of any way to ensure crocodiles stay in it. They are needed for the ambience which also means no fences otherwise how can I enjoy it when unsuspecting peons fall in?
I'd go with piranha at a pinch if they were in game but sadly they are not.
Any suggestions on how I can resolve this artistic dilemma?
