What’s your name, title and what you do for The Sims Studio?
My name is Azure Bowie-Hankins and I’m an Assistant Producer for The Sims 3 Store.

What is Hidden Springs? Is it a Stuff Pack/Expansion Pack?
Hidden Springs is a brand new downloadable world only available through The Sims 3 Store. You’ll have a brand new world to explore with new families, new locations and a couple of new surprises and objects as well.

What’s included in it? Will we get new places for our Sims to live, places to explore?
Hidden Springs a luxurious resort town located near a lake and surrounded by picturesque mountains. The town is famous for its spa resort spots and there are rumors of a mythical place located in the woods where Sims can discover a bit of magic! I’m not going to tell you exactly where it is but somewhere hidden in the town your Sims can find the Fountain of Youth! The Fountain of Youth is a brand new object that your Sims can use to decorate their home and make a wish or two. They should be careful what they wish for because it might just come true!
