Sims 3 seasons

The Sims three seasons adds seasons of course, and there are new ways to die like dieing of the heat, or dieing of the cold. Now fireplaces have uses plus aliens are back, if your Sims gets abducted by an alien, it has a chance of coming back. Sometimes when it comes back it is pregnant (even if a male gets abducted) the child will be half alien, half human. There is also rain and it will water your plants for you, if you have a simbot outside when it is raining it will get damaged.
