>>5271370difference there is those are like Battle bases and fortresses being transformed into. Basically they are turning into a playset and not just a static building. It is basically two different modes of play in one, either play with one great big massive toy or you can turn it into a playset to play with using a bunch of smaller toys that interact with it.
Turning into just a building, is a different story. could probably work in isolated examples done well, but not a full toyline.
