Seasons

There isn't much of a choice in this, all for seasons will be rotated. But saying that, there is a cheat that will allow you to stay in winter, also there is an object that is included in with Seasons that will tamper with the weather. Be careful with winter, there is a glitch at the moment that are killing sims. It hasn't happened to me yet, mainly because I haven't really play winter. But I did heard that they are aware of the issue, and is working on it.

Seasons Cheats can be found here.
