While placing a deco school, I realized there was no playground deco for the neighborhood. I looked and looked with no luck. So- here is some neighborhood playground deco. I extracted the merry-go-round, tower, slide and swing. I'm not the happiest with the textures but probably won't change them at all. If you would like different textures, feel free to change them for your own use! (Or share them if you'd like.)
NOTE: At least one EP (any EP) is needed for this to work in your game. All can be found under Landmarks. All can be placed anywhere, even on lots.
