It could be a great introduction to the metaverse. Imagine adding the interior spaces by making the doors and windows openable. Then allow for more and more interactions. A lot could be done by algorithms (image recognition, etc.), but I think a lot of users would be interested in "building this new world". Adding procedurally generated spaces through portals would be a great next step. We are not far away from being able to "create a castle described by X in Y mixing painting style of Z and sculpture style of Ź". Maybe transforming between these styles and others in time.
