Maybe rich villages will attract more snooty characters, and town that doesn't sleep will have more jocks? I think it was confirmed you can choose who will come to your village, so maybe you will get more requests from these animal types depending on which village you choose.
That might be it.
I am just hoping the island changes with the seasons or else not allow bugs and possibly fish. That would be way to easy to earn money, going to the island at night and catching palm tree bugs, unless the only stays daylight all the time it would be fine.
