I just picked this up last night and it is living up to the hype from my perspective. I believe it is voxel based and I am not even a fan of voxel games, but it has almost looks like a nice pixel art game. So far I am enjoying the exploring and building although the snap-to on house parts is a bit twitchy to line up.
I spent the first night standing out in the cold holding a torch to keep from freezing because I was too slow to build what I needed like a fire and shelter, thank the gods it wasn’t raining hehe. I spent part of the next day stuck in my house because of a crazy rainstorm…it was pretty neat.
