Add lots!
Lots would be areas of land that you buy that you can build in, whether its baby size or king size, or any other creative size you can come up with. The bigger the lot size, the more money it costs. Lots would be personal, unless you make ti public. If its public, people could join either by saying something like /join lot [lot name] or maybe like this big lobby list of a bunch of lots. This would prevent people from randomly building and making the Deep Wilderness look sloppy. Developer, don't ask people to not do something, because they WILL do it. Instead, take action, and make it so they can't do that. Hope you like my suggestion.
Thanks for the idea. Not sure how I feel about restricting building, but will consider it.
