Reading about it seems truly sandboxy and pretty dang neat. I like the idea of your actions being able to effect the world, especially when they put this in:
"Everything you do, see, create, harvest, or explore may a have huge impact on the world around it. What seems like a unique design on a weapon could be part of a missing puzzle for a gateway to a hidden realm. Your actions may draw the attention of mysterious entities, for better or for worse."
I'm always a sucker for exploring, so any game that rewards exploring is worth checking out in my book really. I also like the idea that they want their UI very minimal but you can craft shit to bring stuff to your UI. It's like a souped up version of minecraft. I just want to see how the community works in multiplayer together for sure. Crafters, builders, warriors, etc.
