well, since this game is voxel-based I figured the devs could take the oppurtunity and allow us to build underground. Of course there is an issue with the camera, but I think that's just a bump in the road. Anyways, I'd like to not only be able to dig underground areas out, It would also be cool if caves could naturally be there, to explore, kill monsters, and take over. Perhaps they could contain rare ores. Anyways, I'd love to see this implemented, and as I said before, because the game is voxel based, it would be crazy to pass up the opportunity.
