As the seasons change, so do your Sims and the world that they happily live in. In Sunset Valley (and any other world that comes with Sims 3 and its many expansions, including the recently released Supernatural), you’ll witness the surrounding foliage begin to turn into a lovely reddish and orange hue. As the temperature drops, your Sims will bundle up in their outer gear to avoid catching a cold.
Each season lasts about seven sims days, but that can be toggled anywhere from 3 to 28 days, depending on your preference. If you like fall as much as we do, you can keep it set permanently so that it will feel like October, year round. Weather effects can also be toggled, so if you want, it can snow at your command.
