Well, turns out that world I found that I mentioned earlier didn't do wonders for me, so here we go!
I'd like a unique world that needs absolutely no spawners, community lots, etc. Only empty lots. Make a good variety of all the available sizes.
I'd like there to be 3 "areas"
A suburban area with plenty of "basic" trees, mostly Black Gum trees.
I'd like a mountainous area (make it partially sloping, but all lots are totally flat), with tall mountain trees and bushes. Try to make it have a nice view of the beach area, which I will now explain...
A small beach area with palm trees and those large flower bushes.
Try to make the island have a unique shape.
Once again, absolutely no community lots. (Well, a pond if you want, for aesthetic pleasing).
This world would be entirely for building / construction purposes.
The name can be whatever, just something catchy.
That should be all
Oh, and if it really matters, I have all expansion packs (for tree/bush purposes, but you likely should only need base game.)
