Sims 3 Worlds

So, anyway, i've lately been getting readdicted to this game even though I sort of despised it at first because I felt I wasted money on a preorder for the PC release of the game. I kind of treasuring how awesome it is by the project i'm working on for it. It's actually rather interesting. I'm making a city using the Sunset Valley layout and i'm not even near done because of how much planning I have to do.

So, I want to hear what your favorite world is? Is it from an EP? Or did someone make it?
