@shayleajay - I would add that Aurora Skies can be redone to be a Japanese world. It is fairly representative of Japan's northern island of Hokkaidō. That's just one example. I find the world to be a very cheerful place. Also, red is my favorite color and there is lots of it in AS. I find I am very happy playing there and I love this world. <3
Midnight Hollow comes with the toy store content and you can sell things in a store or just have a store in your town. I loved much of the content that comes with this world but I have not had time to play in it. I was building Cotes d'Ambonnay with my friend, xSorcier, when it was released and we did use some of the content in it to build our French medieval world.
You might want to look at all the content the worlds come with to help you decide.
