So CVG has posted a Q&A about Generations with EA producer Ryan Vaughan.
Q: So far we’ve had three expansion packs for The Sims 3. What new features will the fourth expansion introduce?
A: With The Sims 3 Generations, we’ve added tons of new age specific content that will not only allow players to create more interesting Sims, but it will allow players to tell deeper, richer, and more complete stories with their Sims and their families. From a child’s imagination, to a rebellious teen’s angst, to an adult’s Mid-Life Crises, Generations is packed with loads of new life moments that your Sims shouldn’t be without!
