I love the sims 3! I play it at least 3 hours every day....
I love making towns from scratch. I downloaded create-a-world a month ago, and figured out how to do that. I made a town, and filled it with people and animals
I play it also too. After I fill the town, I make a couple, and then I do a legacy with them. I started one not that long ago. I do it alphabetically. (First couple both have A names, their kids have B names, their kids have C names.....) My B generation are teens right now, I haven't been playing them very long yet. (The furthest I've ever gotten was when I played the sims 2, I got to P)
I also love the pets. My legacy family has a great dane, mastiff, and three of their puppies.
I haven't done too much with horses yet though....
