I have sims living in a variety of worlds and enjoy each one for what it offers. Currently, I have sims in Midnight Hollow, Barnacle Bay, Sunlit Tides, Moonlight Falls, Bridgeport, Starlight Shores, Dragon Valley, and two custom worlds Pixie Gardens and Sanctuary (based on Oasis Landing but turned into a homeworld)
I prefer smaller worlds as my current puter doesn't like large ones or ones that are too busy. I use mostly EA worlds, but have a folder full of player-made worlds that I downloaded and will eventually play when I get the desktop fully loaded and ready to play. Some of those worlds that I have tested seem to put more stress on my laptop than it needs.
My favorite EA world is Moonlight Falls. Love the small town atmosphere, the old fashioned houses and the empty lots that I can plunk down favorite builds of mine.
I have not found the perfect world yet. I tried making one in CAW and my puter again didn't like how large I was making it. Someday... :wink:
