Question regarding the games Virtual Villagers A New Home & Lost Children?

I received in the mail a 50% off coupon from a gaming site and I was wondering if you thought it would be worth it to purchase the game "Virtual Villagers: A New Home?" I have "Virtual Villagers: The Lost Children" and I love it!!! I have hours upon hours of fun. Would I be disappointed in A New Home after playing The Lost Children? What are the differences and do you think I will have just as much fun with A New Home that I'm now enjoying with The Lost Children?
