Amazing expansion pack, however before you buy I bought the Limited Edition a week after the release date - the limited edition content (a venue and stage) won't work as it expired on the 6th March. So you are basically getting the normal game. The price is great and possibly makes up for this, as it is a lot cheaper than other sites.
The world is similar to Hollywood, and there are lots of exciting new venues including a karaoke bar and different arenas for your sims to perform at. They aren't rabbit holes either so you can go into them and watch your sims have fun!
I would have given it five stars but the limited edition content isn't avaliable anymore.
