maybe check them out to see if you like them and if you like it buy stuff to put in the castle. :-D
They do that already. You can just click the preview button to see what the castle looks like and then decide whether you want it or not. For the crowns castles click the magnifying glass.
I think that there should be a castle that has themes from different worlds. It could be similar to the fire house- a central tower with five levels (One for each world of the first story arc-Wizard City, Krokotopia, Marleybone, Mooshu, and Dragonspyre. Grizzleheim is a side world and Celestia is going to be part of the next story arc.) and one room on each of the five levels. The rooms would have portals in each of them that take you to a outdoor area that looks like Wizard City, Krokotopia etc.
