No. They are not usable for the popular utilization. We have enough land, we have enough plots to go around. Now, let's supersize the continents! For we already have land for a region. We don't need any other lands, because they will not be available to the region at large. New lands are useless if you can't make use of them. If we are going to use them as decor, then they shouldn't exist.

Only the continents that we have should exist. Because that is what we are using, and there's plenty to share. Supersize them, and make it a planet.
