The problem I have with worlds is, they feel like they're only meant to be played once or twice. Like they're not meant to hold your attention for longer than a single playthrough. They could be a nice place to live, but that's all down to aesthetics or lot size. It's the same thing with many of the festivals: they're all so bare-bones and provide almost no unique experiences, and once you do them, there's nothing of substance to make you come back a second time.
I think Mt. Komorebi is the only world that's well-developed in this regard; you can go on hikes, train to go up the mountain (and eventually climb to the summit), take part in sports, go swimming and do things you can do in other neighborhoods.
