Jilerel: Some time ago it was mentioned a feature was going to be the ability to form small towns and build homes (for a considerable amount of money, ofc) for the purposes of role play. I don't know if this is still a thing that is planned, but frankly models like this would be completely brilliant for it. I don't know if anyone's played the Elder Scrolls games, but in it you have the ability to purchase a house in each city and each house has a different build. Perhaps with something like this, you could have an NPC that is an "architect" who will sell different models, with the prices based on the sizes of the homes, which would be applicable with your work here.
Just thoughts. All of that said, fabulous work man. Freakin' awesome.
