The next Sims 3 expansion pack will add a host of new activities for your sims at every stage of their lives. Young sims can build treehouses, teenagers can attend their school prom, and fully grown sims can have a full blown mid life crisis that allows them to change their hair style and colour, and hopefully blow all their savings on a collection of sports cars.

As well as being able to throw new events like expensive wedding ceremonies and teen house parties, The Sims 3: Generations will also add a collection of new hobbies and activities will let you accidentally kill your sims in a series of new and spectacular ways.

Experimental chemistry sets will be a new source of fun and horrible explosive death for your sims, but safer activities will also be available, including the option to throw bachelor parties. Younger sims will be able to pull pranks, plant toilet bombs and have imaginary friends. A new memories system will let you keep track of your sims' major life events, and post their progress on Facebook.

Generations is due out this spring, for more information on the new expansion, head over to the official Sims 3 site.

The Sims 3 is now on Steam, bringing interactive soap operas, dysfunctional families and suburban nudist colonies to your Steam account. The game's many expansion packs are also on Valve's digital download service, including World Adventures, which lets you take your sims treasure hunting in exotic and often booby-trapped locations, and Late Night, which lets you take your sims out on the town. There's also a bundle deal offering the Sims 3 and all five expansions for half price. I'm off to build my sims a glorious mansion, and then delete all the doors and watch the carnage unfold.
