Everything Island 2! ? I haven't tried the first one, yet, but this world is pretty nice. It's NO CC, so you don't need to worry about unnecessary lag. I also have a filter installed, so the graphics will look slightly different than without it, but nonetheless, it's still a pretty great of a neighborhood. The quantity of premade townies weren't that high when moving in, so that can be a plus, if you like. I brightened the pics a bit since the in-game quality was a little..."off".
Anyways, I took some photos:
