I REALLY like this idea. On Facebook, it would probably cost...
50k~75k gralat. That's a LOT. But I would honestly enjoy this, although $25 or a sh*tload of Gralat is a bit much. I think it should be $10 and 30k gralat. Still pricy, but considering you're talking about your own town/tower/field/whatever, it's fitting. It should have some better way to utilize getting furniture, too. Filling this monster of a house would be a pain otherwise. It should have an open to public option, kick all, clear furniture, and a few types of Center. There would be War maps, which can also easily be used to be a simple forest or something. There would be Snow, Lava, and Forest. Then the inside could be a huge open space, tower, or be a luxury area, with balconies and such. I love this idea!
