The first expansion for the Sims 3 added 3 vacation worlds based Egypt, France and China. You can chill out and enjoy the vistas or do "adventures" involving things like talking to locals and exploring tombs. It includes mummies! Probably the last time we are goign to see them as they are considered kind of xenophobic now, we'll see. It adds photography, karate, and cellars. It's not a top tier expansion for me and I personally only ended up going one time to each location, but it's always nice to have an option to explore new areas and cultures.
