Depends on sims I want to play and things I want to build
but i pretty much have favourite spot in every world that I have built about million times over while ignoring all the other lots in the world
but i also am trying to get rid of that habit and realize new favourites everytime I build on lots i thought were totally awful before because they were just badly used
as example i used to really detest spire apartments cause its just so unneededly big but i divided it in half and padumts suddenly its one of my favourites
i used to really hate the empty house in grims quarry but padumts i made new boring suburban with aliens in it and its perfection and it perfectly lines so i could create government spies to spy on them from one of the apartments (which btw i also often sort of hate because first level can't be used but other than that its awesome and the boring appearance just adds to the vibe)
i guess the short answer is just : I like lots that have to be rediscovered because it makes me hyped to continue discovering best purpose for them
initial answer would be: I've built in forgotten hollow about 1000 times more than other worlds but i mean thats just given as its my only spoopy world for spoopy mansions which i love
