I really hoped by now we would have gotten the options to save and share worlds. I get we can get rid of everything then save it to be played later. But I never tried that since I would not be able to remember what save that would be ten years from now. And since the game saves a picture of a household instead of a world, I wondered how that works since you have to have a Sim in the world to save it. Well, or at least to see the picture of a Sim so it could jog the memory.
My vote is for options to save worlds. Like New Crest is empty but if you spend time fillling it, then come back two years later, would you remember which save that is? I didn't, and my vote is for a save and share world templates. And no Sim needed in the world as a placeholder, either.
Or, if not possible the code and tools to delete all houses, all trees, all Sims and no more requiring a Sim to be created first before we can even enter a world. Please also, put back the bulldozer into world panel view like in 2014 so I don't have to enter lots before I bulldoze. It used to be next to the build feature at the bottom.
