After spending some time there, it becomes increasingly unsettling and disturbing in a very subtle way. It's the Uncanny Valley done on purpose.
So I leave to go somewhere else, where the kagouti don't make robot noises, where the trees don't have a metallic glimmer, where the water splashes instead of making an oily "plum!" sound, where there is no clockwork in the sky.
Unfortunately, there aren't many reasons to come back regularly.
IMO, Sets, leads, and motifs will contribute to short term popularity, but convenience is king for long term popularity.
