Biomes and Structures to encourage exploration

What if the further away from spawn you went, this crazier the world became? One way to encourage traveling is to put exclusive Biomes far from spawn. These could be giant forrests, and scarred, and gouged craters. Structures can be the same, with more wild and radical structures generating away from spawn. This would make people explore for these Biomes and structures. And with the Wild update aiming to liven up the world, this can become reality.
