Sunset Valley in general pretty much annoys me. It seems in Sunset Valley, there's no variety, and the same things happen, with the same Sims, over and over again. (Fiona is always reading a book when I send a Sim to the hospital to have her baby, Stiles is standing there, freaking out. The Bunch Family is having a picnic in central park, the lack of Insane Sims, Marty and Justine are playing catch, Xander is at the gym.) There's nothing different happening within the Sims. Naturally, I prefer the other default town, Riverview. That town has more interesting situations with Story Progression, and, different, I may add. Plus, my favorite classic Sims are in that town.
I think I'm annoyed that there's only two Insane Sims per world, in Sims 3. We need more Insane Sims.
